Would it make sense to statically link fftw3, instead? To do that I
think all you would have to do is delete (or temporarily hide) the
shared library, build scipy, then the shared library back. Then all
users of your egg would gain the benefits of fftw3.
I'm sure there is a more elegant solution involving copying the fftw3
static library in a special directory and using environment variable
magic to make it visible and fink NOT visible to the scipy build. But I
don't know the magic (if I did I'd use it to build matplotlib).
