Hi,

I tried to install it and experiment a little bit with it. I have
problems running web interface. After adding 

options         P1003_1B_SEMAPHORES

to my kernel and recompiling apache with threads, I've got the
following error:

Mod_python error: "PythonHandler mod_python.publisher"

Traceback (most recent call last):

  File "/usr/local/lib/python2.4/site-packages/mod_python/apache.py", line 299, in HandlerDispatch

    self.__block = Condition(Lock())

error: can't allocate lock


Could you point to me what I am missing? Thank you very much.
