Can you check which version of Python/distutils. If it is a version python
that does not come with distutils, we can count it out.

Yes, and they will complain to JH if they are failing to install JH's
binary RPMs. The best we can do is explain the motivation of NOT
providing binary RPMs. If that is not sufficient for some, we can
only advise that they switch to Windows or pester their distro
providers for RPMs of the latest NumPy.

There are two ways to do this:

(1) Extension( ..., extra_compile_args = [ "-O17" ], ...)
This will append the optimization level 17 to the compiler flag
(the last -O option counts).

(2) export CFLAGS=-O3; python setup.py build
This will append -O3

The result of (1) and (2) is gcc .... -017 -03

PS: distutils may look intimidating at first, but it is really
simple compared to automake/autoconf. The disadvantage is that
it is not very well tested.
