Hi Jochen,
this is great news and I'm eager to try it out.

I have a few questions:
1.) Do you support both single-threaded and multi-threaded ffts in one
installation, or would it work (only) with the kind of fft library
pyfftw finds at installation time ?
2.) I would like to incorporate pyfftw into my image analysis package
(Priithon). For that I provide binary packages for Linux 32bit + 64
bit + windows + Mac-OSX. The question now is, if I could share the
same pyfftw files - as generated by "python setup.py install" on one
system - between those systems ?  I could see this working because you
are using ctypes. On the other hand, the README file talks about many
things that are done at installation time.
It even says, that the FFTW_PATH environment variable is overwritten
if the situation at installation time would somehow compete with it.

Thanks for making your work available to us.
