Guido,
Didn't expect a reply on Sunday. Thanks.
The Zope distribution includes its own distribution of Python 2.1.1+ complete
with the standard lib/test suite (see way below). I added a print to the
Zope install module to verify it was using Zope's version, it was:
Zope is installing with: 2.1.1+ (#2, Dec 21 2001, 17:47:18)
[GCC 2.7.2.3]
You are correct, of course. The errors I mentioned are in all Python
distributions. My complaint here is that they are stopping the Zope
installation, at least they do for me. The correction is not to fix the py
modules as I suggested -- that was my expedient way to get Zope to install --
but to figure out why they kill the Zope installation.
I went back and did reinstall again , verified that it does happen, and
captured the output:
Here is the output if I don't change the test modules

There were errors during Python module compilation.

The install was a failure, it did not create the start and stop scripts.
Here is the output if I correct those test routines:

This worked correctly!

Hope there are enough clues here to assist in tracking this down.
Thanks again for your help,
