I'm confused by this one. I find "64-bit Kernel Extensions: No" in the System Software Overview text area when Software is selected in the Items table, but I don't see a 64-bit option either in the tree under Software or under Software/Extensions, where I tried to find it.
But I verified that my Python is 64-bit by calculating log-base-2 of sys.maxint and finding it to be 63 (this is a technique I saw recommended in several places). I also see that `file -L' on /opt/local/bin/python2.6' yields `Mach-O 64-bit executable.' `file' on /usr/bin/python just says "multiple architectures" but does not say 32-bit or 64-bit; but it also won't work with Skype4Py, which makes me think it, too, is 64-bit. Still not sure of a next step. (And no, for those who were around long enough ago to know this reference, "next step" was not intended as an Apple platform reference :-) .)
