You just answered your own question. Use Darwinports (whatever that is).
Support for HiPE on OSX/x86 in the vanilla OTP tarballs is only partial.
It requires the mach_override stuff, and is totally unsupported since
(1) it does weird things (mach_override), and (2) we (the HiPE group)
don't have OSX/x86 machines.
Just ask whoever's in charge of Erlang in Darwinports to enable SMP,
or get the source code for their patched Erlang package and enable
SMP yourself. It probably just needs ./configure --enable-smp-support.
