*sigh* never mind. It's TWW's fault. They install an older version of zope.interface (3.3.0), then smash sys.path together in such a way that their packages *always* appear toward the front of the list. The only way to "override" their stuff is to delete it or move it out of the way. Skip -- https://mail.python.org/mailman/listinfo/python-list
