A first attempt at this emits the message:
/usr/lib/python2.7/distutils/dist.py:267: UserWarning: Unknown distribution option: 'install_requires'
warnings.warn(msg)

This is because it's using setuptools instead of distutils.

Near the top of your script, try replacing

from distutils.core import setup

with

from setuptools import setup

Even better, import from setuptools, and if that raises an ImportError import from distutils.core instead
try:
from setuptools import setup
except ImportError:
from distutils.core import setup
