3.0 on Debian Wheezy: stuck

When using the setup-kolab patches I recently checked into the git 
repository, the configuration of a *.deb based installation runs through to 
its end.

However,
1) http://MYSERVER/kolab-admin shows the admin interface, but I can't log in 
using "cn=Directory Manager" - "internal System Error." Shows up in the 
browser. The dirsrv log shows what's attached below. I also think cyrus 
might not be configured/running.

2) http://MYSERVER/roundcubemail does'nt exist at all - the apache config of 
this setup has me puzzled ...

I'd highly appreciate any hints on how to verify the services involved step 
by step and also educated guesses what might be misconfigured.

Thanks for your time.

Sincerely, Joh
