Hi, It worked perfectly for me. I just got a couple of deprecation warnings when starting zope (should use re and not - unmaintained - regexp module). As far as I can follow the traceback, the BTree problem is off topic for your issue. I suspect you did not install Python 2.1.3 from source, or you did a python 2.1.3 binary install without the python-dev kit. It seems that error is raised because the proper Makefile.pre.in has not been found.

Is this my problem ? Thanks, Dirk
