You will need to use gfortran for a Universal build of Python on Tiger. g77 does
not build Universal binaries. See the instructions I give here:

What instructions? (This has nothing to do with your problem, but I am unaware
of instructions which tell you to modify Lib/fftpack/setup.py and would like to
nail down any false information).
