This patch mentions:

but "python setup.py config" fails to compile with the message:
unable to execute _configtest.exe: No such file or directory
Somehow, the optimization compiler flags are getting set to -O3 which
only seems to
be set for the emx compiler platform...
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
