A similar error occurs when attempting `python setup.py install`. I'm doing this in a virtualenv with python2.7.12. Changing setup.py to look for simply `twisted` resolves the error.

Looking at release dates, I suspect that package management has simply moved from underneath this project. Logging here for visibility; I will probably fork then try to dockerify this and update deps.

works fine in ubuntu 14.04 (I was attempting this in OS X homebrew)
