#!/usr/bin/env python

and

from sys import version_info
if version_info[0] < 2 or version_info[1] < 4:
     raise RuntimeError("You need at least python2.4 to run this script")

IMO you shouldn't struggle with it too hard. If the user's python 
version is not appropriate, don't hack its interpreter mechanism to do 
the work you need. Anyways, you should not check for specific python 
versions but for modules/APIs/builtins whatever and *then* you may raise 
an exception pointing the user to the fact that is python version does 
not fit your needs.
