i have used the modules from the debian lenny repository, maybe 
something has the wrong version?

Python Version: 2.5.2-3

i have tried easy_install -UZ trac in the virtualenv. it successfully 
unpacks the egg to the cache, but the same error occurs.

i have tried with SetEnv and python_option in the virtualhost config 
which works for the rest of kforge. but in the case of the trac plugin 
it does not seem to get obeyed. is there any point in the code where i 
could set it?

best regards,
Gert
