I just fixed this for Python 2.5.  We'll have to include a staticly  
linked copy of libz22 in the installer, just like we're doing for  
bsddb. For 2.5 I'm doing the same with sqlite (new in 2.5) and zlib  
(2.5 uses functionality that isn't present in the Panther version of  
zlib).

Its getting more and more clear that I can't get way with not  
updating the 2.4 installer :-(.
