pants don't seem to like {{py26}} and {{python-zope-interface-3.5.2}} combination. It likes {{py27}} and {{python-zope-interface-3.5.2}} combination though. IOW, the tests don't fail when using {{py27}} with {{python-zope-interface-3.5.2}}. 

The fix is to upgrade zope interface to v4. To use Aurora with {{py26}}, one should upgrade python-zope-interface.

{code}
sudo yum uninstall python-zope-interface
sudo yum install python-zope-interface4
{code}

Opening this ticket to document it for users running Aurora on OEL6.
