what I am trying to get done first is a responder for my application

I got the lastest version of Twisted from subversion ( 13109 ) and
installed it by doing a
python setup.py all install

now I get this error on all my code ( and the mdns.py code from your sandbox )

+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
    from twisted.internet import protocol
  File "/System/Library/Frameworks/Python.framework/Versions/2.3/lib/python2.3/site-packages/twisted/internet/protocol.py",
line 18, in ?
    from zope.interface import implements
ImportError: No module named zope.interface

is there a dependancy on Zope with Twisted 2.x?

I did find the protocol.py file the line from zope.interface import implements

what am I missing here?
