On my Mandrake-8.2 the RPM for fftw consists of a 'user' package and
a 'devel' package. To rebuild SciPy the 'devel' package is needed (this may
be also the case on other distro's).

The relevant files for the rpm packages are:

[packer at venus packer]$ rpm -ql fftw | grep lib
/usr/lib/libfftw.so.2
/usr/lib/libfftw.so.2.0.5
/usr/lib/libfftw_threads.so.2
