python-geventhttpclient fails to build because python-zope-event and
python-zope-interface aren't installed.  They're imported by
python-gevent, so I think they should be moved from its native-inputs
to its propagated-inputs.  Should I file a patch to fix this as a
separate report or should I send it to this one?
