Good.

> PPC is supported when building universally.  At Apple, we build many things "3-way Fat" meaning i386, x86_64, ppc.  (By the way ppc refers to 32-Bit PPC, ppc64 refers to 64-Bit PPC)
> So it is possible to build something 3-way fat, however "as of this instant in time" the MacOSX-port is only 2-way fat (i386, x86_64).  Apple no longer supports PPC, so you probably won't see any Apple engineers supporting PPC, however if you want to support PPC, you can do so.  I believe our stance is we won't stop anyone else from supporting PPC, and we will do our best to make it possible for PPC to be supported, but we (Apple engineers) won't do any direct support for PPC.

I don't have access to PPC machine, so I can't help, but some people
on openbsd-port list could be interested since they build OpenBSD port
on OS/X PPC.
They will probably have some patches/code to provide, they should pass
by CLA, it there contributions could be kept on this branch.
