Darwin is the open source part of Mac OS X that has been ported to PPC and Intel 
platforms.  It's mainly just the core of services like a Linux kernel.  Other 
people have added the rest of the GNU/Linux stuff so you basically get Linux 
without the Linux kernel (I know, it is confusing).  ELF is a standard binary 
distribution type, but now that I think of it, Darwin probably doesn't support 
it anyway since they use Mach-O binaries (again, more confusion).  So, the short 
answer is that Mac OS doesn't exist on Intel, but the long answer depends on 
what you really mean by Mac OS.  In any case, it doesn't appear that you would 
be able to run S+ on Darwin for either Intel or PPC because of the ELF vs. 
Mach-O difference in their binaries.  The only likely solution is if a Mac OS X 
version of S+ was released.  Sorry to get your hopes up.
