This means that you never explicitly merged them, they are not in world and are no longer required by anything else. There are normally three reasons: - you merged something that needed these packages, then unmerged them later, leaving these dependencies orphaned - you merged something else that used them, and in a recent update they are now using something else that provides the same functionality - they were required by some USE flag you once had, and you have now changed your USE, so the deps are no longer required. You'll need to look at each package and figure out if YOU need them, as we can't tell you that. I might think that you don't need your wife under any circumstances, and you might strongly disagree :-) I once knew what hashalot does. I forgot. It's something to do with cryptography pwdb is used as a password and user account configuration thingy. Looks pretty important :-) attr provides extended attributes to ext2/3 and XFS file systems, used by selinux and posix capabilities. If you use these features, you already are aware of it. When you figure out which ones to keep, it's best to put them in your world file. Either edit /var/lib/portage/world and stick the name at the end, or run 'emerge -n <package-name>' -- Alan McKinnon alan dot mckinnon at gmail dot com -- gentoo-user@lists.gentoo.org mailing list
