I'd like to pare world down to just the things that make a difference. Remove the line from the world file and run emerge depclean -p If depclean wants to remove it, it was probably installed as a dependency of something you no longer have. You can also use equery depends ,packagename to find what packages depend on it. -- Neil Bothwick WinErr 007: System price error - Inadequate money spent on hardware pgpnMi5W8hH49.pgp Description: PGP signature

I had to go through my machines by hand doing the emerge/depclean/revdep-rebuild process I outlined in an email on this subject to Grant this morning. It took me a while to get it done.

Yes, _unmerging_ anything in this list could be extremely dangerous. It might lead you to unmerge python or even glibc...and then you would be really hosed. I would consider the output a guide for manually (and cautiously!) editing your world file! -Richard -- gentoo-user@gentoo.org mailing list
