The shebang only works on unix variant systems.  Windows simply ignores it and 
goes by the filename extension instead.  It's relatively safe bet that every 
modern *nix system that runs cgi scripts will have python in /usr/bin/python, 
if this isn't the case then you have two choices

a) Write in the README with your app to change the first line of the cgi 
script to be appropriate.

b) Write yourself a simple sh script that finds python and executes it based 
on a few simple possibilities or a configurable line or something of that 
nature.

I would go with a)
