Unfortunately, this is a variation of an old issue that hasn't yet been 
fixed (http://bugs.python.org/issue1099).  The simplest workaround is to 
include the --enable-universalsdk option to configure, so something like 
this:

./configure --enable-framework --enable-universalsdk=/

That has the side effect of causing a universal build (ppc and i386).  
If you don't want to have that, you could go in an manually edit 
Makefile.pre.in and eliminate the "test" and else clause starting at 
line 487, in other words, always use gcc to make the framework library 
and not libtool, and then rerun configure.  I'll make sure the issue 
gets resolved.

Another solution is to use the 3.2 32-bit installer for Mac OS X from 
python.org:
