USE flags will never affect anything that you need (to run the system), though it may affect things that you want (for your own ease and comfort). That I knew but the global settings may enable support that I do not need/want, gnome being one of them. snip So, add -gnome to your global USE flags-- oh, I see you already do-- and then do an emerge -uaDNtv world (to recompile all apps compiled with gnome support without it), and then an emerge depclean -p and then an emerge depclean (or unmerge various packages individually) to remove the now-unnecessary GNOME libs that were previously installed. You might also want to disable gtk, and gtk2. When you say you have a lot of gnome stuff installed, what precisely do you mean, anyway? You seem to have -gnome in your USE flags, so it's not as if you have applications installing unnecessary (for you) GNOME libs and such. And surely you did not explicitly install GNOME-- or did you? If so, unmerge it (if you emerged gnome or gnome-light, this will only unmerge the meta packages, not the applications installed by the meta packages), and then do an emerge depclean -p (and then an emerge depclean, or unmerge the packages individually) to remove the now-orphaned GNOME dependencies. I just recently added that -gnome. I didn't have it in there when I emerged everything else on my system. Since I didn't know any better before, I want to correct that now. I was going to just do a quick reinstall but I seemed to have it removed by seeing what depclean returned and removing things I didn't need manually, mostly gnome stuff. If I did a reinstall, I was going to copy the kernel, kernels config, world file, and a few config files that I changed over and let it do its thing. I did that a while back when I changed drives. Make.conf was one of those config files too. But you may have a number of packages that depend natively on GNOME/GTK libs; and if so, then you're just stuck with those, in the same way I'm stuck with kdebase and qt if I want to use K3b. If that's a real problem for you, investigate what programs those may be and see if you can find a KDE or generic X-based alternative (for example, if you use gcolor2, a GTK/GNOME color-chooser, you may want to switch to kcoloredit, the KDE color chooser). snip This means nothing to me, since I have no idea what your system does or what you do with it. Do you need optional java and javascript support globally, for example? Do you develop java or javascript? Maybe you do; I don't know-- at least then having the gcj USE flag enabled would make sense (since gcj is the gcc support for a java compiler, afaik). Myself, I don't, so I disabled that globally, and only enabled it in /etc/portage/package.use for those programs I know I want java and javascript support for (firefox, basically). I just know I use java so I stuck it in there. I don't develope java stuff though. Java works so I'm not beating it up. It may break for spight. (sp?) Do you do desktop publishing? Do you even use scribus? Do all applications you may or may not have installed that *can* use Scribus actually *need* to have *optional* scribus support enabled? I do use Scribus on occasion. It's easier for me than OOo on some things. And if you don't use a database, why do you have the innodb USE flag enabled? I did install mysql once and then removed it. I guess I missed that USE option when I removed mysql. Thanks for pointing that out. See, you did know something about that USE line. LOL USE flags customize your system to your personal needs, and I cannot know your personal needs-- only you can. So I would suggest reading through /usr/portage/profiles/use.desc and /usr/portage/profiles/use.local.desc to understand what the USE flags you have enabled actually do. Myself, I have an alias in ~/.bashrc, stolen from this list, to quickly scan USE flag definitions: alias useflag=grep /usr/portage/profiles/use.*desc -e So if I do an emerge -uaDNtv world and see a USE flag I don't understand, I can just do a (taken from the k3b USE flags above): useflag sndfile /usr/portage/profiles/use.desc:sndfile - Adds support for libsndfile and make my own decision about whether I want libsndfile support enabled or not. I've gotta say, that when I install Gentoo, the longest part of the installation for me is in fact not the kernel compilation (that's the second longest), but the scanning of the USE flags and reading of the notes, to make sure I disable what I don't want and enable what I do. I could, of course, just leave everything be, and then fix it all later as you are now doing (that's easy enough), but I'm a recovering perfectionist as well, so I like to take the time and get it closer to right the first time. I do regularly use the -v option

That's the way it's supposed to work, afaik.

I am a bit worried about using the option they posted, the -* at the beginning of the USE line. I may disable something that I need then. The first thing you need to understand is that USE flags enable/disable *optional* support for supplemental applications. USE flags will never affect anything that you need (to run the system), though it may affect things that you want (for your own ease and comfort). For example: I run fvwm-crystal (not KDE, thus, and also not GNOME, though GNOME is installed). However, I do use the KDE program K3b for CD burning. emerge -pv k3b These are the packages that I would merge, in order: Calculating dependencies ...done! [ebuild R ] app-cdr/k3b-0.12.10 +alsa -arts +css -debug +dvdr +encode +ffmpeg +flac +hal -kde +kdeenablefinal +mp3 +musepack +musicbrainz +sndfile +vcd +vorbis -xinerama 0 kB As you can see, I have kde and arts support diasabled. Since I do not use KDE (or even have more than a minimal KDE installed), adding such support would be pointless (bloat), since enabling the arts USE flag would bring in aRTs (the KDE sound server, which I wouldn't use even if I did use KDE), and enabling the kde USE flag would bring in k3bSetup2, which is a nice little utility to correct the permissions on the CD/DVD burner if necessary, but it's not really mission critical enough to warrant bringing in the additional KDE backend required to support it (if the permissions need to be changed, I can do it myself in 15 seconds, I don't need a GUI from a DE that I don't even use just to do that). But you can see from the dependency list that in order to install K3b, I must install kde-env, kdebase, kdelibs, and kdesu; those are /hard/ dependencies, requried by the application in order for it to run at all; the applications/libraries installed by the *USE* flags noted are optional: Runtime Dependencies k3b-0.12.9 |= app-cdr/cdrdao - 1.1.7-r3 kde-base/kde-env3 kde-base/kdebase |= kde-base/kdelibs - 3.3 kde-base/kdesu media-libs/libsamplerate media-libs/taglib | = media-sound/cdparanoia - 3.9.8 media-sound/normalize = x11-libs/qt - 3.3* *css* media-libs/libdvdcss *encode* media-sound/lame *encode* media-sound/sox *ffmpeg* media-video/ffmpeg *flac* media-libs/flac *hal* sys-apps/dbus *mp3* media-libs/libmad *musepack* media-libs/libmpcdec *musicbrainz* media-libs/musicbrainz *sndfile* media-libs/libsndfile *vcd* media-video/vcdimager *vorbis* media-libs/libvorbis virtual/cdrtools *alsa* media-libs/alsalib *dvdr* app-cdr/dvd+rwtools So the necessary KDE backend for the program to run is installed, just not any extras that I don't necessarily want to use. That's what USE flags do. I use KDE for my desktop. I plan to have OOc installed along with java and that sort of thing. I don't have any database software installed, that I know of anyway.
