Ian Bicking's virtualenv allows me to have isolated Pythons for each application I build, and lets me decide whether or not to include the global site-packages in the isolated Python environment.

I haven't tried it with Zope, but I'm guessing that the following should work nicely:

1. Using your Zope's Python, make a new virtualenv, either with or without --no-site-packages
2. Drop your Zope into the virtualenv
3. Activate the environment with $VENV/bin/activate
4. Install any needed site-packages
5. Run your Zope using the Python now at $VENV/bin/python

This has worked brilliantly for managing Django projects with various versions of Python, Django, and add-ons.

This article seems to go into more detail on the specifics of Grok and Virtualenv, but the generalities should apply to Zope as welll.
