I sent Peter a copy of a shell script to build the library as a Universal library. It worked flawlessly for me in the past, but when I tried it recently I had issues with it. However, the primary options needed to build for different architectures are in the script.
I post this since anyone else who is looking for this can request a copy of the script from me.
