Hum, IMHO it's a bad idea to change the python link to another Python
version (other than de distro default).

Can put the Python version in script header (and make it executable)
#!/bin/env python2.5

Can write a small script shell starting the Python script with the
ad-hoc Python version.

The magic code.

Just rm -rf *.pyc from your own scripts directories, they will be rebuilt.
