Hi Jon,

I saw this a month or so ago when I tried to compile fftw on OS/X 
10.3.<something>.  

I fixed it by hacking the fftw source code.  Seems that there is some
conflict between the "flat" and "non-flat" shared library model (or
something like that), and that fftw and/or libtool runs afoul it.

I fixed it on fftw-3.0.1  (probably the same on fftw-3.0.1-fma) by
these drastic steps:

fftw-3.0.1/libbench2/getopt-utils.c:  remove it and replace with an empty file.
fftw-3.0.1/libbench2/getopt.c: remove it and replace with an empty file.
fftw-3.0.1/libbench2/getopt1.c: remove it and replace with an empty file.

E.g.,   cp /dev/null getopt-utils.c

Apparently os/x doesn't like it when there is more than one entry
point with the same name.
