Portage should handle transitive dependencies no problem, so my guess is that you have your system for a long time, and over the period, this is what happened: - package-old.version, pulled in dependency-some.version, which depends on further-dependency-some.other.version - package was upgraded to package-new.version which doesn't depend on dependency-some.version anymore - you have dependency-some.version on your system, which depends on further-dependency-some.other.version, but isn't really reachable by the current dependency tree - depclean tries to get rid of those, but produces a very scary output with seemingly useful packages listed. I cannot be 100% sure on that, so I recommend you do the following steps 1. make sure USE flags for all your packages are properly set, don't use USE=flag emerge package, actually edit /etc/portage/package.use 2. do a emerge --deep --newuse --update world so that all packages pick up the correct USE flags and hence dependent libraries. 3. emerge -pv depclean, it'll explain what pulled what in. 4. At this point, it should be safe to emerge depclean to get rid of the obsolete dependencies 5. revdep-rebuild > > Try "equery depends =gcc-3*", without the quotes obviously. > > > > If none of the packages you installed depends on gcc-3*, you should be > > able to get rid of it safely. > > [m3000][root][~] equery depends =gcc-3* > [ Searching for packages depending on =gcc-3*... ] > sys-libs/glibc-2.6.1 (>=sys-devel/gcc-3.4.4) > sys-libs/libstdc++-v3-3.3.6 (>=sys-devel/gcc-3.3.3_pre20040130) > www-client/links-2.1_pre28-r1 (sys-devel/gcc) > > It looks like nothing depends on gcc-3*. looks safe to me. Don't forget a revdep-rebuild after the "emerge -C =gcc-3*" HTH. -- Joe -- [EMAIL PROTECTED] mailing list
