Citing from http://effbot.org/zone/python-compile.htm:
Python?s byte code is portable between platforms, but not necessarily  
between Python releases.

Unless your python module is for only one specific version or you know  
the python interpreter version on all installation targets, you better  
leave it up to the installer to compile the module (the page shows  
trivial code in python to do this).

Something different would be to get complete application binaries.  
However, that somehow defeats one purpose of using Python.
