Scipy seemed to build ok, but when I call anything in fftpack, I get the error at the end of this post.  I recompiled fftw (2.1.5) and ran make check (or test?  they all passed) before rebuilding scipy, but the error remains.  Any help would be appreciated.

Offhand, I'd suggest using gcc 3.3 to compile Scipy and FFTW, not gcc 
4.0 which is the default on Tiger. Python 2.4.1 is compiled with gcc 3.3.

$ sudo gcc_select 3.3

If that doesn't work, lemme know, and I'll look into it more deeply.
