Last time I nearly whacked my machine, 'emerge --depclean'said I could get rid of of attr and acl. I figured I was using neither attr nor acl, I would 'merge -C' them. If you do a 'equery depends attr', you'll find coreutils depends on it, as well at acl. Without coreutils, you can forget emerging and a many basic functions of the machine. Long story short, I had a copy of the missing libraries in an another install directory, managed to copy them to the right directory, and saved dozens and dozens of hours it would have taken my to reconstitute my machine. You do get a warning, and heed it well. Bill Roberts
