[Discuss] Python script question

[gaf at blu.org (Jerry Feldman)]

A coworker of mine has a Python script set up as:
#! $PATH_TO_PYTHON/python
... python code

It is not unusual to have commands like this. Mailman does this with
several of its commands. The issue here is that he needs to use an
environment variable to call the python interpreter. We certainly can do
it a messy way:
#! /bin/bash
$PATH_TO_PYTHON/python foo.py

But this would require a wrapper script.

Or he can use an explicit path to the python interpreter.
#! /usr/bin/python

The problem here is that the version of python he uses MUST be
encapsulated in our company's product.
#! /mnt/fubar/versionxyz/bin/python

But this will possibly differ with each release of our company's product
since we maintain a number of releases here.  Some other solutions is to
set up symlinks in the local directory. 

Any ideas on how to get the loader to expand the environment variable
after the #!??
