And, if you copy the libgfortran.a file to somewhere else, say ~/staticlibs/, you can force the linker to use it instead of the .dylib such that your users don't need to install gfortran. $ export LDFLAGS="-undefined dynamic_lookup -bundle -arch i386 -arch ppc -Wl,-search_paths_first" $ python setup.py config_fc --fcompiler=gnu95 --arch="-arch i386 -arch ppc" build_ext -L ~/staticlibs/ build ... $ file build/lib.macosx-10.3-fat-2.5/scipy/odr/__odrpack.so build/lib.macosx-10.3-fat-2.5/scipy/odr/__odrpack.so: Mach-O universal binary with 2 architectures build/lib.macosx-10.3-fat-2.5/scipy/odr/__odrpack.so (for architecture i386): Mach-O bundle i386 build/lib.macosx-10.3-fat-2.5/scipy/odr/__odrpack.so (for architecture ppc): Mach-O bundle ppc $ otool -L build/lib.macosx-10.3-fat-2.5/scipy/odr/__odrpack.so build/lib.macosx-10.3-fat-2.5/scipy/odr/__odrpack.so: /System/Library/Frameworks/Accelerate.framework/Versions/A/Accelerate (compatibility version 1.0.0, current version 4.0.0) /usr/local/lib/libgcc_s.1.dylib (compatibility version 1.0.0, current version 1.0.0) /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 88.3.7) The pointer to /usr/local/lib/libgcc_s.1.dylib is innocuous. That's just the first place it will look for that library at runtime. There's one in /usr/lib that appears to be picked up and used just fine. Problem solved.
