It returns None on the PowerPC box, and '/usr/lib/libiconv.dylib' on
the Intel box.  The question is, why?

The same library is in the same place on each machine; they are both
running the same operating system.  They are both using the
Apple-supplied Python that comes with the operating system.  This is a
bug somewhere in ctypes.
