Nice.

That's not exactly true. Different library *names*. And not compared
to Linux, but compared to "what scipy assumes to be the FFTW
installation". 

I just mad a whole bunch of soft-links in /usr/local/lib to represent
the following (from scipy/setup.py):
,----
|     # FFTW (requires FFTW libraries to be previously installed)
|     double_libraries = ['fftw_threads','rfftw_threads','fftw','rfftw']
|     float_libraries = map(lambda x: 's'+x,double_libraries)
`----
That is, you need libfftw_threads.so, librfftw_threads.so, libfftw.so,
librfftw.so plus the according set of 's'-libraries. I guess it is
obvious what these should link to (depends on what you have:).

In the long run this has to be replaced by some detection scheme what
the FFTW-libs are named on the local system, I'd say.

Greetings,
Jochen
