[erlang-questions] Trouble compiling erlang on OS X intel

I'm having trouble compiling Erlang R11B-5 on OS X.4 on an Intel  
MacBook Pro. It fails saying that it can't find "mach_override.h",  
which doesn't appear anywhere on my machine.

~/Desktop/otp_src_R11B-5% ./configure --enable-smp-support --enable- 
threads --enable-kernel-poll --enable-hipe --prefix=/usr/local --with- 
ssl && make
gcc -mdynamic-no-pic -g -O2 -I/Users/dking/Desktop/otp_src_R11B-5/ 
erts/i386-apple-darwin8.10.1  -no-cpp-precomp   -DUSE_THREADS  - 
prototypes -Wmissing-prototypes -DUSE_THREADS  -D_THREAD_SAFE - 
D_REENTRANT  -Ibeam -Isys/unix -Isys/common -Ii386-apple-darwin8.10.1/ 
opt/hybrid -Ii386-apple-darwin8.10.1 -Izlib -Ihipe -I../include/ 
internal -I../include/internal/i386-apple-darwin8.10.1 -c i386-apple- 
darwin8.10.1/opt/hybrid/hipe_x86_bifs.S -o obj/i386-apple- 
make[3]: *** No rule to make target `mach_override.h', needed by `obj/ 
i386-apple-darwin8.10.1/opt/hybrid/hipe_x86_signal.o'.  Stop.
make[2]: *** [opt] Error 2
make[1]: *** [hybrid] Error 2
make: *** [emulator] Error 2

If I do the same without --enable-hipe it works, but the Erlang from  
Darwinports has hipe and it works just fine (although it doesn't have  
SMP support, which is important to me), so I know hipe works with OS X.

I see that Darwinports actually ships with mach_override.h:

% find /opt -name mach_override.h

I also see that Darwinports has some other files necessary for Erlang:

% ls /opt/local/var/db/dports/sources/ 
mach_override.c         mach_override.h         patch-toolbar.erl

So is there a generalised OS X patchset that I'm missing?
