Thanks Matt - it's in the tarball
( ./gnuradio-core-2.1/src/lib/general/gr_fft.cc )
I just don't know how to use it.

$python
>>>from gnuradio import gr
>>>dir (gr.fft)
AttributeError: 'module' object has no attribute 'fft'

during compile ./configure finds fftw3f ok
gr_fft.o compiles ok    but I'm lost with how to access or
use it in Python.
