Can't find out why check_style.py fails in #20.

[stonemary]

#20 's build is broken and I could not find out why.

Cleaned up everything and pylint runs 10/10. However running check_style.py errors out.

I suspect this is a PYTHONPATH problem again. subprocess is probably not passing in environment variables correctly. However I tried manually passing in PYTHONPATH in subprocess.check_output's env parameter, and it still errors out.

At this point, my options are limited to:

1. Wait for someone to fix check_style.py
2. Fix check_style.py myself - which I would properly do for fun, and then change it to something like tox =P

Please suggest.
