I finesse the issue by installing it in my main Python installation first.
Then I copy the pyxml tree into the Zope\bin folder - that way, it ends up
in the same relative position relative to Zope's python.exe as it was in the
original installation.  Workd fine.  You should be easily able to afford the
extra disk space.

The only downside is keeping both copies of pyxml in sync if you apply any
patches.  But I haven't found that to be a problem in practice.

Incidentally, pyxml has a small bug in xpath, and another one that keeps the
xslt function document() from finding local files on Windows systems.  I
posted bug fixes for these two on the pyxml list a few weeks ago.  If you
can't find them, email me and I'll send them to you (I don't have them here
on this computer).
