It's safe to remove emul-linux-x86-* to see what happens next; and fixing it is trivial. So: - remove those packages - fiddle make.conf - emerge world using -p and inspect the list If you don;t like what you see, revert your edits and remerge emul-linux-x86-*. They are binary packages so the emerge is rather quick. As long as you didn't re-merge anything else in the interim, nothing will break -- Alan McKinnon alan.mckin...@gmail.com
