The problem is that the run-time underlying Open MPI is unable to locate the ssh binary you told it to use to launch your application. Is ssh in your path?

I did the following with openmpi 1.1 and 1.2 alphas now I get the
following error. 

mpirun --mca pls_rsh_agent ssh -np 2 -machinefile
ompimachinefile ./hello_world_mpi
--------------------------------------------------------------------------
No available launching agents were found.

This is an unusual error; it means that Open RTE was unable to find
any mechanism to launch proceses, and therefore is unable start the
process(es) in your application.
