It sounds like you just need to tweak your Python path so that things
inside the prod/ or test/ directory (in the appropriate case) are on the
Python path. Something like
PythonPath "['/usr/prod/'] + sys.path"
is probably correct. Then "import promotions" will work if
prod/promotions/ is a directory.
