I think this is a basic Python question.  If you set your PYTHONPATH
variable to . (period), then when you import a python package it will
look in the current working directory for the package, and then the
standard system directories.  This way, to test both the original and
modified versions, you would do:

  cd \original_project
  trial package_to_test

  cd \modified_project
  trial package_to_test
