 You may get some more information by -echo to see what MPICH doing
 exactly as
 
 $ mpirun -echo -np 2 -machinefile hostlist mdrun -np 2  -s mini
 
 But Which MPI implementation and version are you using? MPICH has
 built-in debugger tools to see where the problem has occured. I'm also
 assuming you gave hostnames properly.
 But as DAvid  suggested just compile it LAM-MPI.
