The problem seems to be the check_output function in the Python
subprocess module. I've used it since it is the new recommended way to
run shell commands. It looks like it was added to the Python
subprocess module in Python 2.7 and I assume you have 2.6. The
corresponding command for 2.6 is commands.getstatusoutput but it's
deprecated and removed in Python 3.

Don't know what the best solution is, either:

1. Require Python >= 2.7, or
2. Try/except and use one of check_output/getstatusoutput

Opinions?
