It seems to build a shared library _fftpack.so in the fftpack
directory of scipy. This _fftpack.so is linked to the fftw2
scipy/fftpack> ldd _fftpack.so
librfftw.so.2 => /noc/users/agn/ext/Linux/fftw2/lib/
libfftw.so.2 => /noc/users/agn/ext/Linux/fftw2/lib/
libg2c.so.0 => /usr/local/lib64/libg2c.so.0
so just calling fftpack might be using fftw.
hope it works! George.
