I don't think that this patch is necessary..  On my Mac OS X 10.3 
machine (comes with Python 2.3.0), webbrowser.py uses Internet Config 
to launch the url (the 'ic' module).  This is basically equivalent to 
the open command.  It works like this:
	* Internet Config is an old MacOS API that's mapped to Launch Services 
which launches the URL with your preferred browser
	* open is a command line utility that uses the NSWorkspace Cocoa API 
which uses Launch Services to launch the URL with your preferred 

I don't think your patch fixes anything, it's launched by Launch 
Services either way.. at least on OS X 10.3.  A patch doesn't do us any 
good against Python 2.2.0 on Mac OS 10.2 if its behavior is broken.  
Apple doesn't update Python between major releases.

You should be able to install MacPython 2.3 in your home directory.  
Don't bother with Fink.
