FFTW is not used anymore in neither numpy or scipy (has not been for several years). If you want to use fftw with numpy, there are 3rd party extensions to do it, like pyfftw

I just d/l numpy-1.8.1 and try to build. I uncomment:

[fftw]
libraries = fftw3

This is fedora 20. fftw3 (and devel) is installed as fftw.

I see nothing written to stderr during the build that has any reference to fftw.
