Okay, Engin reminded me why I originally wrote it to always treat Snow
Leopard as 64-bit: if you have a 64-bit processor, the 64-bit build
will work regardless of kernel type.  However, if you are running a
32-bit kernel, the architecture will always be reported as "i386".  So
we're left with these choices:

1) Make the 'mac-intel-osx-x86_64' platform dependent on the 64-bit
kernel, so everyone who needs the 64-bit build has to change kernel
2) Keep the current behavior, and people running Snow Leopard on
first-generation Intel Macs will need to use the 32-bit binary

Neither is ideal; the latter has additional problems for SBGrid, due
to the way we 'alias' the architecture when the 32-bit installer is
used.  Ben, did you decide what to do about CNS?
