Hi!
The Kolab2/Gentoo project made a first "official" step in the direction of portage integration today:
http://article.gmane.org/gmane.linux.gentoo.devel/52431and
http://www.gentoo.org/proj/en/kolab/index.xmlDo not expect portage integration to happen soon though. This is still a long way to go. But it would already help if the cyrus imapd, c-client and php would find their way into the main tree.

Cheers,
