A package usually resides in its own namespace. If import will be done 
like this:

import reportlab
import rl_addons

These are two packages. In setup.py they get defined more or less like this:

packages = [
         "reportlab",
         "rl_addons",
         ],

You can assume that the directory structure will be as defined before:

src/
test/
fonts/ ;)

So you may find the parent directory from runAll.py like this:

import os.path
parent = os.path.join(os.path.dirname(__file__), os.pardir)

A developer should also register his working version on his machine like 
this:

$ python setup.py develop

This makes programmers live a lot easier ;)
