PyGame download and install script for OS X Lion

Closed - This job posting has been filled and work has been completed.

Job Description

I need a script or two to download, and run a PyGame application.

If this is done within 24 hours of accepting the job, there will be a $100 bonus.
if it is within 48 hours, there will be a $50 bonus.
Done means code sent to me via email or Skype.

Skype me for any questions on the username 'fluxorz'.

The script, once ran with minimal clicking or typing required, should automatically download and install pygame dependencies and run main_3.py from https://bitbucket.org/lukestanley/yviz/get/default.zip

A tiny bit of Apple script if needed would be ok too but mainly bash and Python are prefered.

Previously I have used a .command file archived into a tar file to easily deploy a bash or Python script to a Mac OS X computer by providing a user with a link and very minimal download instructions.
(As document at http://superuser.com/a/305848/19381)

The Pygame application main_3.py should have all dependencies installed and then run without crashing.

Only assume the user has a regular setup, and doesn't have any developer specific tools installed, for example, only assume they have the default OS X Lion Python setup.
