OK, well I need universal binaries, so I'll try to move forward  
rather than backward.

I appreciate the time you've put into this.

This is a very good clue.  Here is the sys.path from a working  
application built with the same version(s) of all the tools:

'/Users/delza/sampleapp/dist/sample.app/Contents/Resources', '/Users/ 
delza/sampleapp/dist/sample.app/Contents/Resources', '/Users/delza/ 
sampleapp/dist/sample.app/Contents/Resources/lib/python24.zip', '/ 
Users/delza/sampleapp/dist/sample.app/Contents/Resources/lib/ 
python2.4', '/Users/delza/sampleapp/dist/sample.app/Contents/ 
Resources/lib/python2.4/plat-darwin', '/Users/delza/sampleapp/dist/ 
sample.app/Contents/Resources/lib/python2.4/plat-mac', '/Users/delza/ 
sampleapp/dist/sample.app/Contents/Resources/lib/python2.4/plat-mac/ 
lib-scriptpackages', '/Users/delza/sampleapp/dist/sample.app/Contents/ 
Resources/lib/python2.4/lib-tk', '/Users/delza/sampleapp/dist/ 
sample.app/Contents/Resources/lib/python2.4/lib-dynload', '/Users/ 
delza/sampleapp/dist/sample.app/Contents/Resources/lib/python2.4/site- 
packages.zip'

And here is the sys.path from a plugin:

'/Users/delza/Library/Screen Savers/PastelsView.saver/Contents/ 
Resources', '/Users/delza/Library/Screen Savers/PastelsView.saver/ 
Contents/Resources', '/Users/delza/Library/Screen Savers/ 
PastelsView.saver/Contents/Frameworks/Python.framework/Versions/2.4/ 
lib/python24.zip', '/Users/delza/Library/Screen Savers/ 
PastelsView.saver/Contents/Frameworks/Python.framework/Versions/2.4/ 
lib/python2.4/', '/Users/delza/Library/Screen Savers/ 
PastelsView.saver/Contents/Frameworks/Python.framework/Versions/2.4/ 
lib/python2.4/plat-darwin', '/Users/delza/Library/Screen Savers/ 
PastelsView.saver/Contents/Frameworks/Python.framework/Versions/2.4/ 
lib/python2.4/plat-mac', '/Users/delza/Library/Screen Savers/ 
PastelsView.saver/Contents/Frameworks/Python.framework/Versions/2.4/ 
lib/python2.4/plat-mac/lib-scriptpackages', '/Users/delza/Library/ 
Screen Savers/PastelsView.saver/Contents/Frameworks/Python.framework/ 
Versions/2.4/lib/python2.4/lib-tk', '/Users/delza/Library/Screen  
Savers/PastelsView.saver/Contents/Frameworks/Python.framework/ 
Versions/2.4/lib/python2.4/lib-dynload'

Since the ../Contents/Frameworks/Python.framework/Versions/2.4/  
directory does not contain a lib directory, these paths are broken.   
I'm trying to track down where they are set, which appears to be in  
the bootstrap Objective-C code for setting the RESOURCEPATH  
environment variable.  Does that sound reasonable?
