Tuomas VesterinenI am not a great expert on this But I think you need to use the Redhat alternatives system to switch between versions rather than trying to change things manually. as i understand it the Alternatives system sets up and changes various symlinks to ensure everything works correctly.
Yes, my first trial is not the solution because byte compiled .pyc files must be produced by the corresponding Python version.
PEP 3147 http://www.python.org/dev/peps/pep-3147 suggests a common solution, but only for Python 3.2 and perhaps 2.7. So I am still looking for hints. Have You some helpful links to those "Alternatives system"?
