About the only time you'd use a versioned python executable name is if 
your program actually depends on that version of Python.

This might be the case if your application includes a C extension, and 
you want to make sure you invoke the version of Python that the 
extension was compiled against (ie. you'd write out the #! line at 
install time to match how the app was built).

If you don't have a dependency like this, using a versioned executable 
name will just cause unnecessary incompatibilities.
