Which sources are you using? The 2.4.x tarballs don't support -- 
enable-universalsdk (and yes, configure won't complain about unknown  
or misspelled options, that's an entirely different subject). Those  
SDKs also don't support mixing --prefix and --enable-framework, the  
prefix argument will be ignored completely. Python 2.5 does support -- 
enable-universalsdk and specifiying other prefixes when using -- 
enable-framework. I have a patch that backports this to 2.4.x, but  
haven't applied this yet because I haven't had time to fully test  
this yet, hopefully I'll manage this week.

BTW. --enable-framework --with-pydebug is all you need, the others  
are either default or deduced from the platform information by  
configure.

And completely off-topic: please don't install your own build of  
python as /usr/bin/python. IMHO this is conceptually bad, but more  
importantly Apple uses python in some parts of the OS (PDF workflows  
for example) and this change could well break that.

What version of the developer tools are you using? And are you  
building on PPC or Intel?

One way to work around the problems you're having is to install the  
binary install of 2.4.3.

Obviously someone must have managed, there's a binary installer for  
the OS :-).  And before you nobody that ran into this problem found  
it important enough to actually tell us about is.
