I now have access to a machine running a 64-bit kernel for testing.

I talked to one of our Mac experts; apparently it's only fairly recently that 
we've been able to use the 64-bit kernels on which "uname -m" reports x86_64 
for the CPU type, which is why our EpicsHostArch scripts weren't expecting 
that as a response.  This has also caused IT problems with other packages, 
which is why all our Macs here have been defaulted to using the 32-bit kernel 
for now.

Oh, and apparently we even have some machines whose CPU is 64-bit capable but 
the bootloader is not and it can't be upgraded.

The edits to fix the startup scripts are fairly simple, I'll put up a patch on 
the Known Problems page shortly.

Thanks to everyone who helped track down this little issue.
