After today's world update, the eix-update command, run under root,
failed to "open the database file '/var/cache/eix/portage.eix' for writing."
Nevertheless, the same command, run with ordinary user privileges, completed
without error.
Obviously, while updating, the priviliges are dropped to another user
(root shouldn't be overused anyway). In this case, they are most likely
dropped to user "portage". Try changing the owner and group of the cache
to "portage".
$ ls -al /var/cache/eix/portage.eix
