I see, and for you guys, the ability to have more than one version of
Zope2 installed at the same time is a killer feature?

Yeah, in that case you can't depend on the python-zope.* packages till
python packaging in debian sanely allows more than one library version
installed at a time.

Which is probably not gonna happen soon. Pity.

Thanks for taking the time to work through this, but I guess I finally
understand where the real problem is.
