I am not sure if the fftw etc are expected to build on Windows. I am
assuming so. If they don't, we should be fixing them, anyways.
Fixed install order.

The bug was that the fftw/numpy were being placed in the package before
fixup_bundle was being run. That script then attempted to fixup these
numpy/fftw shared libraries too. The fixup_bundle is not designed for
that.
