Workaround for distutils bug in python 2.7

[xeor]

There is a weird bug in python 2.7 that causes a NameError when trying to install this package using run_setup in distutils..
https://bugs.python.org/issue23426 seams related, but does not work in this case.

Here is the error it fixes..

In [1]: from distutils.core import run_setup

In [2]: run_setup('setup.py', ['bdist_egg'])
---------------------------------------------------------------------------
NameError                                 Traceback (most recent call last)
