[OMPI users] ompi_info command not working

[Shafagh Jafer]

HI,
i installed openmpi-1.2.7 and ran the two examples ring_c and hello_c and they 
worked fine. but i can not see any result when i issue the "ompi_info" command. 
Does this mean my openmpi is not configured right?? why do i get correct 
results from the examples then? 
Please help.
