I'm trying to compile and run the graphlaughs example from big nerd ranch.

http://weblog.bignerdranch.com/?p=19

However, when I build the project they setup.py script fails here:

from PyObjCTools import XcodeSupport

Has this gone away? Why? 

Also, I've noticed that older PyObjC projects tended to follow the pattern of starting up via python and 
now the XCode templates have a main.m that instantiates a python interpreter and loads the .py files.

1. Why did things change?
2. What's the easiest way modify the graph laughs example and get it up and running? Have the changes to PyObjC made its approach
outdated?

Thanks,
