You were able to build OpenBIOS on Mac OS X? If so, how? Every attempt I made has failed. I'm using GCC 4.0.1. Could it be a problem with my compiler version?

You cannot build OpenBIOS with Apple's gcc 4.0.1. The 'gcc' installed by Xcode builds Mach-O binaries, not ELF binaries. You therefore need a cross-compiler and `./config/scripts/switcharch cross-ppc`.

I compiled the following in order, all of which were the latest stable versions:

GMP 4.3.1 - note: on ppc64 host supply ABI=mode32 to its configure script or it may build a 64-bit library that gcc later chokes on

MPFR 2.4.1

binutils 2.20

GCC 4.4.2

For GCC configure options please refer to Blue Swirl's post. I used --target=powerpc-elf, but it was recently discussed whether --target=powerpc-eabi is better or equal.
