It is compiled from C. The comment in fft.py says, "The underlying code for these functions is an f2c translated and modified version of the FFTPACK routines."

f2c is FORTRAN to C. So you will have to look at the source for Numeric or numarry to find the source for fftpack. For Numeric you can look here:
http://www.scipy.org/cvs/viewcvs/map?rmurl=http%3A//scipy.net/cgi-bin/viewcvsx.cgi/scipy/Lib/fftpack/
which seems to have the fortran files.
