I'm working only on Windows, and I never had any problems with the
numpy installer. And until recently, I never tried to build it myself.
It is easier to install additional packages once numpy, and numpy
distutils are properly set up.

One problem on Windows is to get the path correct, when I'm building
scipy or scikits or any other package with C-extension, I only use
MinGW, and I don't have cygwin installed. On my old computer I had
cygwin, and I read stories that you shouldn't have cygwin on the
Windows path, since some programs got confused with conflicting
Windows and cygwin versions.

Just a guess:
>From your error message, I would think that python distutils finds
your cygwin installation, instead I would hide it by removing it from
the windows path and work only with MingW.
