Kolab on FreeBSD

I want to install Kolab on FreeBSD 10. It seems there are no precompiled packages available, so I have to compile from source.

On Kolab's Git server the latest Kolab server available is version 2.3.4 (3 years old) and Kolab is now at version 3.4. Many other repositories are available, though.

My first question is: Which of the available repositories (if any) is needed to compile a Kolab server?

To see if I could get any hints I cloned the kolabs-doc repository. Unfortunately, when trying run the included MakeFiles I get errors:

make[1]: publican: No such file or directory

even though there are plenty of files named publican.cfg in the subdirectories.

Am I missing something in the compilation?
