Be careful, because emerge --regen takes a lot of time and it's not recommended for rsync users as rsync updates the cache using server-side caches (most of users of portage are rsync users). Rsync users should simply use emaint (or eix-sync) to regenerate the cache. It's probably only users of very large ebuild repositories should try emerge --regen.
