Download bz2 and install the library "somewhere", download the  
python2.4 sources and extract the sources for the bz2 module. Then  
write a setup.py that builds the bz2 extension and use that to  
replace the one that's on your system. Don't forget to add '-Wl,- 
search_paths_first' to the extra_link_args, otherwise ld will prefer  
dylibs over static libraries and will hence pick up the system bz2 no  
matter what.

Not this week, I've spent way too much time on an annoying problem in  
the x86 port of PyObjC and want to do some python hacking for change.  
I'll be happy if I manage to test a backport of the universal python  
changes to the official python 2.4 tree and check that in this week,  
and even that will probably have to wait.
