[Users] MPI trouble on 64-bit Mac OS X 10.6.7 (fink version)

My code works totally ok with MPI on my linux machine, but as I'm porting to my Mac, I find that MPI isn't working right. I'm using the OpenMPI version from fink) A simple "hello world" MPI program works fine (proof at the bottom of this message), but Cactus does not.
That is to say, e.g. an 8-processor run ("/sw/bin om-mpirun -np 8 ....") results in 8 processes, but each processes thinks it's processor 0, and that there are no other processors.
Any ideas why this might happen?
Thanks,
Scott
I'm using Cactus version 4.0.b17 (Compile date: May 20 2011 (11:13:49)).
Cactus run:
> mpirun -np 8 ~/Cactus/exe/cactus_texmex sep20a0.5fmrbbh97_cactus.par

....and so on.....
Yet a imple program works:
The simple example which works fine is...
> cat hello.c
#include <stdio.h>
#include "mpi.h"
int main(argc, argv)
int argc;
char **argv;
{
int rank, size;
MPI_Init(&argc,&argv);
MPI_Comm_rank(MPI_COMM_WORLD, &rank);
MPI_Comm_size(MPI_COMM_WORLD, &size);
printf("Hello world! I am %d of %d\n",rank,size);
MPI_Finalize();
return 0;
}
> mpicc -o hello hello.c
> which mpirun
/sw/bin/mpirun
> ls -l /sw/bin/mpirun
lrwxr-xr-x 1 root shawley 9 May 20 10:55 /sw/bin/mpirun@ -> om-mpirun
> mpirun -np 8 ./hello
Hello world! I am 0 of 8
Hello world! I am 6 of 8
Hello world! I am 3 of 8
Hello world! I am 1 of 8
Hello world! I am 2 of 8
Hello world! I am 4 of 8
Hello world! I am 5 of 8
Hello world! I am 7 of 8
