All of it works with 10.3.9 out of the box. Anything else is unsupported and requires using gcc-3.3 for the PowerPC side and gcc-4.0 for the Intel side.

Otherwise, it depends on what reason you're doing it. I'd probably use platform.processor(), which returns 'i386' or 'powerpc'.. but it returns 'powerpc' for ppc64 as well, so you might also want to check platform.architecture()[0] to be safe. You could probably also do these with sysctl. -bob _______________________________________________ Pythonmac-SIG maillist - Pythonmac-SIG@python.org http://mail.python.org/mailman/listinfo/pythonmac-sig
