Hi Travis and Travis

I managed to build and install fftw both threaded and single precision
I also got the python build and install going
However there seem to be two bugs
1. the Numeric.pth file in the site-packages directory ends up being 
empty!
thus Numeric will not be found , easily fixed by somebody with enougth
python experience
to know about the .pth files.
2. the fftw.so fftw-module is not found by the FFT2.py module in spite
of being in the
same directory namely site-packages/scipy/fft

regards

Moritz
