I saw this too.  I worked around it by uninstalling ZODB 3.2 from Python's 
site-packages (specifically MultiMapping.so.)  The source of the problem 
is that some code in Zope 3 uses MultiMapping as an optional import, but 
Zope 3 doesn't actually provide a MultiMapping module.  If it happens to 
find a copy of ZODB 3.2 or earlier, something breaks, probably related to 
ExtensionClass.  Two things should happen:

- Zope 3 shouldn't try to import MultiMapping.

- Someone should find out if this is a problem for Zope 2.8.
