ImportError: Twisted requires zope.interface 3.6.0 or later: no module named zope.interface.

Using a vanilla OSX virtuabox image, I run the following script:

https://raw.github.com/kpdyer/fteproxy/87052d23e3b0004d738551d1e7ca28314609258d/BUILDING.osx

Then, when running the inplace version of fteproxy we have success:

osxs-Mac-Pro:fteproxy vagrant$ ./bin/fteproxy --mode client

Client ready!

However, when we attempt to run the pyinstaller-bundled version we get:

osxs-Mac-Pro:fteproxy vagrant$ ./dist/fteproxy --mode client
Traceback (most recent call last):
  File "<string>", line 23, in <module>

ImportError: Twisted requires zope.interface 3.6.0 or later: no module named zope.interface.

So, fteproxy depends upon obfsproxy which depdends upon twisted which depdends upon zope.interface.

Apparently this is a well-known issue with pyinstaller but they have no near-term plans to fix it:

Thanks to the suggestion here: https://groups.google.com/forum/#!msg/pyinstaller/POYwzd-VrHU/ycbGN85sUD4J, the following hack works:

sudo touch /usr/local/lib/python2.7/site-packages/zope/__init__.py

This solution assumes we're using the homebrew version of python.
