I am not interested in Python, but looked over your changes to see what functionality is missing or different in GNUstep. One thing that I noticed was that this code expects that result of a copy operation on an NSMutableArray is a mutable array, and that on GNUstep you had to use mutableCopy. If this is true we should change the GNustep behaviour and add a test case for this.
Any other interesting stuff you found while working on this?

Hi Everyone,

Are you worried that your Objective-C code is too fast?  Too readable?  Too 
maintainable?  Well now you can fix that, by adding Python!

Attached is a diff against PyObjC that allows it to build with GNUstep[1].  
This allows Python to use Objective-C objects, to subclass them, and to pass 
Python objects to Objective-C.  There are still some bugs, but please try it, 
play with it, and see what breaks!

With PyObjC, it's trivial to export a Python interface for scripting your 
Objective-C code, so you can allow Python programmers to write plugins and so 
forth without needing to modify your Objective-C code.

[1] Tested with libobjc2 1.5, GNUstep-base and corebase from trunk on 
Linux/PowerPC and FreeBSD/x86.
