I am trying to run server for iphone using http://www.raywenderlich.com/3932/how-to-create-a-socket-based-iphone-app-and-server
My machine is mac 10.6.8 Python versi
The problem is that an __init__.py file is not present under zope directory so this directory is not scanned for imports.
Creating a blank __init__.py file under zope directory will do the trick.
I solved this error in UNIX by browsing to the zope directory by executing:
$touch __init__.py
I can confirm that this works also with virtualenv pip installation of zope interface
