changing from python2.3 to python2.4

[Uwe Mayer]

I've written a little application which uses the bang-line 
#!/usr/bin/python

to call the interpreter. As python 2.4 comes distributed with other distroes
this breaks my application as its modules are installed
in /usr/local/lib/python2.3/site-packages/... and python2.4 does not look
there.

How do you suggest dealing with this:
- is calling /usr/bin/python2.3 in the bang-line problematic?
- installing into both python2.3 and python2.4 
- rebuilding (re- ./configure, make, make install) the app solves the
problem

Whats the usual way to deal with this?

Thanks
Uwe
