Well it *would* have worked if easy_install didn't go off to download.zope.org 
to find the latest zope.interface package due to a promiscuous 
distribution_links in the ZODB package.  See also 
http://plope.com/Members/chrism/distribution_links_considered_harmful .. Ugh. 
I'll need to re-roll that ZODB egg without the dependency-links and put it up 
there.  I'll post when that's done.
