The problem is that python was compiled with gcc 3.3:

$ /usr/bin/python
Python 2.3.5 (#1, Mar 20 2005, 20:38:20)
[GCC 3.3 20030304 (Apple Computer, Inc. build 1809)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
 >>>

Switch from gcc 4.0 to 3.3 using the command 'gcc_select 3.3'.
You can get a compatible g77 binary (v. 3.4) at HPC for OS X <http:// 
hpc.sourceforge.net/>
