The default is 32-bit, meaning i386 and ppc. The most useful alternative is 'all', which includes all 4 CPU architectures supported by MacOS X (i386, ppc, x86_64 and ppc64). This includes limited support for the Carbon bindings in 64-bit mode as well, limited because (a) I haven't done extensive testing and (b) a large portion of the Carbon API's aren't available in 64-bit mode anyway. I've also duplicated a feature of Apple's build of python: setting the environment variable 'ARCHFLAGS' controls the '-arch' flags used for building extensions using distutils. ........
