It appears to be complaining about your imap line in SERVICES. It's saying
that the address family is not supported. I assume that it's trying to
listen on tcp6 socket.

Try adding "proto=tcp4", like this:

imap            cmd="imapd -U 30" listen="imap" proto=tcp4 prefork=0 maxchild=100

If that works for imap, you'll need to replicate for pop3, lmpt and sieve.

See the man page for cyrus.conf for more information.
