I looked at it when I was looking for a BSD-compatible FFT with support
for prime factors (which fftpack does not handle). As Robert mentioned,
I did not see any compelling reason to bother - the main limitation of
fftpack as used in numpy is support for prime numbers (because you then
get N**2 performances), and kissfft did not support this last time I
checked.

cheers,
