Note that this was a problem on my Linux box as well.

A workaround for this problem in setup.py is to run this simple script 
to create the
config.h file that is failing (probably due to the compile flags):


gcc -fno-strict-aliasing -DNDEBUG -g  -Wall -Wstrict-prototypes 
-IInclude -IPackages/FFT/Include -IPackages/RNG/Include 
-I/usr/include/python2.4 Src/config.c -o mkconfigh
./mkconfigh
mv config.h Src
