You can set environment variables within python, e.g.:

os.environ['PYTHONPATH'] = '/some/path:' + old_path

What I don't know is if child processes invoked through os.popen inherit
that variable on all platforms. However, the subprocess.Popen object takes
an explicit "env" variable for that purpose:

http://docs.python.org/lib/node528.html
http://docs.python.org/lib/module-subprocess.html

So you should be able to use that for the same effect.
