Hi John,

I'm ready and eager to blame Z classes for everything :)

In this case, lets try to force ZClasses to fix themselves up by going 
into Zope at the python command line prompt

% cd lib/python
% python2.1.1
 >>> import Zope
 >>> app = Zope.app()
 >>> app.fixupZClassDependencies(rebuild=1)
 >>> get_transaction().commit()

Hopefully that will do it for you.
