Could you try to run the following simple code to see if it works?

#include <mpi.h>
#include <stdio.h>
int main(int argc, char** argv)
{
    int rank, size;
    MPI_Init(&argc, &argv);
    MPI_Comm_rank(MPI_COMM_WORLD, &rank);
    printf("rank %d\n", rank);
    MPI_Finalize();
    return 0;
}

Even if put the /usr/mpi/bin in front of /usr/bin, it won't affect anything. There has never been any mpi installed in /usr/bin.
