Well actually what I am I thinking is that doing a sync operation, makes portage aware of new packages and when I for any reason give the emerge --update ... command it tries to fetch new packages. Yes, that is exactly what it is designed to do. When portage is asked to emerge something it generates a list of packages to be examined, and it will *always* want to upgrade the entire list to the most recent version (subject to arch and mask/keyword rules). There is no way round this as this is the expected behaviour when you sync something - the result of any sync action is to bring your system up to date with some master system. If you don't want portage to do this, then don't sync so often Although I don't know if any situation forces me to issue update on a outdated portage tree!!! Correct. Portage uses your local copy of the tree. It really couldn't care if it is very new or very old, it uses what you have. You decide when to update the tree, not portage; and you update your tree on whatever schedule you decide -- Alan McKinnon alan.mckin...@gmail.com

At least what happened to me was that depclean removed the sources from /usr/src/ folder but the linux.xxx remained in the disfiles folder. You are confusing the distfile with the installed files. A distfile is usually a tar.gz - it is the package downloaded from upstream. The installed files are whatever the ebuild puts onto the live system. In the case of a binary package like say bash: the distfile is bash-4.2.tar.gz the installed file is /bin/bash In the case of kernel sources, exactly the same rules apply but the details differ: the distfile is linux-3.15.tar.xz (plus patches) the installed files are /usr/src/whatever the version is kernel sources are a special case - portage does no compiling with them. Kernel sources install is defined as unpack the tarball and patches to /usr/src Regular ebuilds define install as whatever happens after ./configure make make install Here's a tip: Go back and read the gentoo docs from beginning to end, all of them. Twice. You are getting confused with gentoo basics and starting to jump the gun because you haven't fully absorbed all the basics.

(I've omitted several sleeps from the /stop/ procedure.) If I left out any of

That probably has a lot more stuff in it than I need; I just removed the
things I certainly didn't need from a copy of the host mtab.
There's a similar init script and mtab for the other chroot.
I've no doubt all you systemd people will throw up your hands in dismay at the
work involved in setting that up. It didn't take long, really.

OK, thanks. I want this to work during an update world and of course the ebuild changes on almost every update, but I guess I am stuck.

If you compile KDE outside Portage, there's a nosound flag, but the Gentoo devs have implemented that to require 'USE=soundpkg, perhaps knowing that it cb happily ignored via '--nodeps'.

I have sound disabled in the kernel no sound pkgs installed ; I have had to install Phonon, but nothing to work with it.

how much do you have to install if you deactivate all use flags for
okular? well, you still have all of qt... and kdelibs and phonon... but
you would loose a lot of the other stuff. vlc support in phonon is as
optional as tiff or chm in okular.
When reading pdf files, one expects images, so tiff and jpeg are
reasonable flags. One does *NOT* expect audio stuff like phonon. And
phonon *DEMANDS SOMETHING*. vlc is one of the options that satisfies
phonon's demands. Or you could choose gstreamer and its gazillion plugins.
I have no idea what you are talking about.
[I] kde-base/okular
Available versions: (4) 4.12.5-r1(4/4.12)^t (~)4.13.3(4/4.13)^t
{aqua chm crypt debug djvu dpi ebook +handbook +jpeg mobi +pdf
+postscript +tiff}
There's nothing in there about audio or video. There's only images and
of those only 4 rational ones are enabled by default plus the help system.
So what is the real problem exactly again?

phonon is not an okular dependency.
It is a deep dependancy. kde-base/kdelibs-4.12.5-r1.ebuild has a
COMMONDEPEND= block which includes =media-libs/phonon-4.4.3. And
media-libs/phonon-4.6.0-r1.ebuild has the following line...
REQUIRED_USE=|| ( aqua gstreamer vlc )
In gentoo, *ANY* kde app which runs on the kde infrastructure requires
phonon, and one of aqua/gstreamer/vlc, unless you resort to ugly hackery
