It would be great if Portage would remove the package from the world profile after doing "emerge unmerge <package>".
I suppose that this would be one case where we could manually tweak the world profile.

*portage-2.0.26 (06 Aug 2002) 06 Aug 2002; Daniel Robbins <drobbins@gentoo.org> portage.py: on unmerge, entries are now removed from the world file if 1) the dependency refers to the cat/pkg being unmerged, and 2) the dependency matches the current version being unmerged and 3) unmerging this package will leave no other packages on this system that will match this world entry. This closes bug #3409
