ImportError: No module named Foundation

I am trying to follow the instructions for the accepted answer to "PyObjC development with Xcode 3.2". I will repost them here since I don't have enough rep to comment on the actual question:

Here's what I have done to get PyObjC working in Snow Leopard:

• Using the Finder, I went to Go > Connect to Server... and connected to http://svn.red-bean.com/pyobjc/trunk/pyobjc/pyobjc-xcode/ as a guest.

• I then made a folder called Xcode on my local system at ~Library/Application Support/Developer/Shared/Xcode/. (You may already have this folder, but I hadn't customized anything for myself yet).

• I copied the File Templates folder from the red-bean server into my new Xcode folder.

• Copied the Project Templates folder to some other place, for example, the Desktop.

• Using the Terminal, navigated to the temporary Project Templates folder on my Desktop and ran this command to "build" the template.:

$ cd ~/Desktop/Project\ Templates/

$ ./project-tool.py -k -v --template ~/Desktop/Project\ Templates/Cocoa-Python\ Application/CocoaApp.xcodeproj/TemplateInfo.plist Cocoa-Python\ Application ~/Library/Application\ Support/Developer/Shared/Xcode/Project\ Templates/Cocoa-Python\ Application

When I try to run the line that starts with ./project-tool.py, I get the following error in Terminal:

 ImportError: No module named Foundation

I am running Snow Leopard and have installed Xcode 3.2.1 and have read that this module should already be installed and working. I've read that you can test if t
