I noticed this bug a while ago and on many versions of gentoolkit, but I can't find a sure way to reproduce it. The best way it seems is to run emerge --sync and run equery for all packages that want to update. Anyway, after syncing today I've got this: note ~ # emerge -pv mplayer These are the packages that would be merged, in order: Calculating dependencies... done!
