Interfacing to the FFTW-library is indeed awful, because of many options
that interact in fancy ways. Making a half-descent OCaml-library for
FFT-routines using the FFTW would probably take a couple of days full-time
(too long for me, I am more into symbolic stuff ;).

You can grab my unfinished attempt from here:
