Sven,

I wish I'd waited to send that previous email.

The first 'gotcha' I encountered when I started using
Python Mapscript and Zope was due to a Python version
difference.  Zope 2.4-6 use Python 2.1.  If you've
been using Python 2.2 (as I had been), you will need
to rebuild mapscript using Python 2.1.

You should be able to use the Python that comes with
Zope, for example:

/var/zope/bin/python setup.py install

Or something like that.  Hope this helps.
