I'm not considering this an error, the job runs without any problems.
The orte_base_help_aggregate set to 0 stops some of the other messages
that occur, which is great, I appreciate that option. But, the option
does not stop the point-to-point message,
which I'm assuming, means that something is happening underneath the
sheets and I'm being told it is getting done. With your
option:

langston_at_alpha:~/OPENMPI/openmpi-1.3/examples$ orterun --mca
orte_base_help_aggregate 0 --mca blt tcp,sm,self -np 2 hello_c
--------------------------------------------------------------------------
[[56072,1],0]: A high-performance Open MPI point-to-point messaging module
was unable to find any relevant network interfaces:

Module: uDAPL
  Host: alpha

Another transport will be used instead, although this may result in
lower performance.
