This suggests that your Python installation is broken, and is relying
upon PYTHONPATH to find the standard library. It should be able to
find the standard library without any PYTHONPATH setting.

If you're trying to use a "non-installed" version of Python, use
PYTHONHOME to tell Python where to find itself.
