Ok, I don't think this one was my fault after all.  ;-)

Appearantly part of the traceback was cut off at some point (perhaps
an exception was caught and then something else was raised).  Here's
an indication of the low-level problem:

>>> import App.Product
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
  File "/home/fdrake/projects/Zope/Zope2/lib/python/App/Product.py", line 37, in ?
    import Globals, OFS.Folder, OFS.SimpleItem, os,  Acquisition, Products
  File "/home/fdrake/projects/Zope/Zope2/lib/python/Globals.py", line 23, in ?
    import Acquisition, ComputedAttribute, App.PersistentExtra, os
  File "/home/fdrake/projects/Zope/Zope2/lib/python/App/PersistentExtra.py", line 15, in ?
    from Persistence import Persistent
ImportError: cannot import name Persistent

Essentially, someone isn't importing ZODB soon enough.  I'm not sure
just where the best place is to add the import; App.PersistentExtra is
expecting that it's already done.
