instalace courier-imap končí chybou

zdravim Pokouším se na mym "prvním" gentoo nainstalovat courier-imap a končí to touhle chybou:

emerge courier-imap

netušíte někdo co s tím?

Jo a narazil jsem ještě na jednu zvláštnost. jako MTA mám postfix a jako POP3 server chci courier a na IMAP zase courier-imap

emerge mi ale nechce courier nainstalovat s tim, že ho postfix blokuje. na jinym serveru mam debian a normálně nemá problém koexistovat postfix s courierem + courier-imap + courier-imaps

S gentoo teprve začínam, ale přijde mi divný, že emerge ani courier-imaps nezná, natož že nechce instalovat courier když tam mam postfix.

Poradíte mi? díky
