Conflict on distros where python3 is the default

[rizumu]

I'm running Arch, which has python3 as the /usr/bin/env python as called from the pyflymake.py

A quick hack I used to get it to work with python2:

-#!/usr/bin/env python
+#!/usr/bin/env python2

Maybe there is a better way that this could be set in the .pyflymakerc? Configuring pyflake to use a python2 virtualenv?

Its not a big issue, but just figured I'd share it in case there is a better solution. Thanks.
