See attachment dep.txt for a list of depclean suggestions. See attachment deplist.txt for output of a script that ran equery depends on all the suggested packages to remove. 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.

I did that before posting. I went through the list, and I've unmerged what I could get away with, and reduced the count down from 74 to 53.
