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
mv config.h Src
