I was looking at doing a fat ppc/ppc64/i386 build.  It seems easy  
enough to build tcl/tk/blt etc fat using Apple's compilers and their  
standard recipe for fat builds of autoconf projects.     http:// 
developer.apple.com/technotes/tn2005/tn2137.html

AFAIK the avcall/libffi problem cannot be sorted for x86_64 because  
Apple have not released the documentation for the calling convention  
yet.  It might be in the pre-release Leopard but I don't have it and  
it would under NDA in any case.

PyObjc contains the source files for ppc/ppc64/i386 libffi, but I  
have not yet figured out the standard libffi build system enough to  
get the new sources to build in the normal code tree.

I am not aware of any avcall ppc64 or i386 Darwin code.
