Thanks for the tip.  I am encountering an install problem.  After I
unpack the tarball in lib/python/Products and restart Zope, when I try
to add an Ordered Folder I get the following attribute error:

Error Type: AttributeError
Error Value: 'None' object has no attribute 'blocks'

and the following trace:
