I think i found a solution, and i'll post it here:
Following ./configure and make all install your open mpi libs and
headers should be in /usr/local/lib and /usr/local/include.
Header Search Paths: /usr/local/include
Library Search Paths: /usr/local/lib
add the following (4) frameworks/libra
HI
I'm not sure if that is a problem,
but in MPI applications you shoud
use MPI_WTime() for time-measurements

If you have the following scenario:

Yay, three cheers for Jeff.
