Thanks Ralf,

I was trying with MSVC 9.0 installed, but got this cryptic error:

   C:\Downloads\numpy-1.7.0b2 > C:\python33\python setup.py build
   ...
   error: Unable to find vcvarsall.bat

After sprinkling distutils with debug statements, I found it was
looking for MSVC v10 (not numpy's fault but the error is most
unhelpful).

Presumably "Microsoft Visual C++ 2010 Express Edition" is
the appropriate thing to download?

Thanks,

Peter
