Hi Adrian,
You may have to ask on the Trilinos mailing list, but we can do some
diagnostics to try and help.
I'm trying to install Trilinos in OSX Mountain Lion, to use it with

I assume this is during the config stage. Try and replicate what it is
doing, which is compiling a really simple MPI program. Something like this
#include <stdio.h>
#include <mpi.h>
int main(int argc, char *argv[])
{
int npes, myrank;
MPI_Init(&argc, &argv);
MPI_Comm_size(MPI_COMM_WORLD, &npes);
MPI_Comm_rank(MPI_COMM_WORLD, &myrank);
printf("From process %d out of %d, Hello World!\n", myrank, npes);
MPI_Finalize();
return 0;
}
with
$ gcc trivialmpi.c -o trivialmpi -lmpi -I/path/to/mpi/include
-L/path/to/mpi/lib
and run it with
$ mpirun -np 3 ./trivialmpi
From process 0 out of 3, Hello World!
From process 2 out of 3, Hello World!
From process 1 out of 3, Hello World!
to check your MPI installation independently from Trilinos. Try and get the
above working by setting the "-I" and "-L" flags if necessary.
We can then figure out how to pass those paths to Trilinos.
Cheers.
