Yeah, from scipy.org.

Yes, I have to use VS 2008. I've successfully built Python 2.5.1 with VS
2008 and I'm currently using it to build other neccessary site-packages

I will try it tomorrow at work. I would use mingw or even cygwin but
unfortunately I have to use exactly VS 2008 and only it.

Sorry for this misapprehension! I meant to say that I'm building 32-bit
numpy for 32-bit Python. The machine I'm using to build it is 64-bit
Windows which has both 32-bit and 64-bit compilers and libraries
installed. For now I'm doing only 32-bit builds.
Tomorrow I will try to build numpy with empty site.cfg and post results
