But what exactly is a 'slotted package',
Slotted means that several versions of a package can coexist at the same system. In the case of qt version 3 goes into /usr/qt/3 and version 4 goes into /usr/qt/4. > how do I determine when a packages is slotted, and where do I read > more about 'slotted'? Have a look at 'man emerge' # emerge -vp qt These are the packages that would be merged, in order: Calculating dependencies... done! [ebuild NS ] x11-libs/qt-4.1.1 USE="..." 27,110 kB ^^^ The 'S' means that it is slotted.

I would recommend app-portage/eix as it gives a clear overview of the available versions of any package. # eix -e qt * x11-libs/qt Available versions: 3.3.4-r8 ~3.3.4-r9 [M]3.3.5 [M]3.3.5-r1 4.1.0-r1 4.1.0-r2 4.1.1 Installed: 3.3.4-r8 Homepage: http://www.trolltech.com/ Description: The Qt toolkit is a comprehensive C++ application development framework. Versions that are prefixed by [M] are hard masked usually because they are broken. They should not be unmasked without knowing why they were originally masked. Versions prefixed by a ~ are masked by ~ARCH i.e. testing and can be used by adding them to package.keyword. eix respects package.* an hence 4.1.0-r1 is shown as stable because of this: # grep x11-libs/qt /etc/portage/package.keywords =x11-libs/qt-4.1* ~x86 As you can see you can specify versions to unmask if you want a testing version of qt-4.1* but stable for any other version. This is explained in 'man portage'. To see why a package is hard masked you have to look in the package.mask files. Packages are masked on several levels. Both general and profile specific. On my system I am using the default-linux/x86/2006.0 profile. # ls -ld /etc/make.profile lrwxrwxrwx 1 root root 48 Mar 10 02:02 /etc/make.profile -> ../usr/portage/profiles/default-linux/x86/2006.0 Therefore packages on my system might be masked in the following locations (note that not all of those files actually exist because no packages are hard masked on some of those levels. Still these are the locations where portage will look.): /usr/portage/profiles/default-linux/x86/2006.0/package.mask /usr/portage/profiles/default-linux/x86/package.mask /usr/portage/profiles/default-linux/package.mask /usr/portage/profiles/package.mask And the reason why qt-3.3.5 is hard masked: # grep -A 2 Qt /usr/portage/profiles/package.mask # Qt-3.3.5 causes a lot of compilation failures. # See bug #106402. ~x11-libs/qt-3.3.5 But qt-4 is not hard masked so it should be working or at least it won't break anything. ;) HtH -- Bo Andresen -- gentoo-user@gentoo.org mailing list
