[SciPy-user] Bug in FFTPACK wrappers

I am still getting errors on mac OSX 10.3.9, python 2.4.1 in the 
ifft(fft(sin(x))) when the fftpack routine is used. The routines in 
the basic package work properly. Does anyone have them working 
properly?

Any pointers on how to find out where the problem is? I think fftpack 
is using fftw-3.x libraries.

I have attached a simple script that shows the difference between the 
basic and fftpack results.
