Looks like it's not linking your MPI libs. Being an MPI moron myself, I
can't be more helpfull, but try looking for -L or -l options in the make
file. Also see if your newly compiled MPI libs are in /lib, /usr/lib,
/usr/local/lib or some other directory that is listed in /etc/ld.conf then
run ldconfig just to be sure.

I hope that helps, Good luck! :)
