Not distutils, but setuptools (or its fork distribute).

The EASY-INSTALL-ENTRY-SCRIPT comment is a hint.

Here's the source code to the latest Distribute:

It's not what you're running because it doesn't do the
'sys.path.append()' bit.

It would help if you could figure out which version of setuptools (or
distribute) you're using.

python -c 'import setuptools; print(setuptools.__file__)'

could give you a hint.

If C gives you enough rope to hang yourself, C++ gives you enough rope to bind
and gag your neighborhood, rig the sails on a small ship, and still have enough
rope left over to hang yourself from the yardarm.
