Kolab 2.3.3 compilation breaks with perl error

[Benjamin Eckl]

Hi all,

I'm trying to compile kolab-server-2.3.3 from source for quite a while 
now. Following http://wiki.kolab.org/Kolab2_Installation_-_Source with 
recent file paths, I'm installing on root partition for testing.

My System is a openvz virtual machine using debian-6.0-x86.tar.gz from 
here: http://wiki.openvz.org/Download/template/precreated

After fixing dependency problems with tcl8.5 (missing) all my luck stops 
here:

No idea what this error is saying me, please give me a hint.
