Hot to get Python executable's path ??

What is the general feeling on executable expectations?
Should python apps:
Detect or get the executable path to python and rewrite shebang (#!) lines
at setup.py time
+ known to work at install time
- need to provide process to update to new Python version if user moves or
removes old version
Run with whatever is provided by #! /usr/bin/env python
+ no need to rewrite #! lines
- at the mercy of whatever is in the path
Code #!/usr/bin/python and expect the sysadmin to create it
- might require sysadmin (user) to create/manage the link correctly
- might not be Windows friendly
In all cases, the app needs to determine that the interpreter under which it
has been invoked is an appropriate version and has needed components.
Are there other solutions and tradeoffs?
