And just to be sure - /usr/local/lib is in your ld_lib_path, yes?

You might also check the permissions to ensure you can read them. Also, check "which mpirun" - let's make sure you are running the one you think!

Thanks Ralph.
My prefix is /usr/local and I see that is present in /usr/local/lib directory.

Check you <prefix>/lib directory - there should be an openmpi directory under it, and that should have a bunch of libs in it. One of those should be

Is it there?

I had the OMPI lib directory added in /etc/
I also added it in LD_LIBRARY_PATH, but it made no difference.
When I call mpirun, should I specify the MCA in command-line?

I suspect your LD_LIBRARY_PATH doesn't include the OMPI lib location

I am running mpptest over Open MPI (v1.5.4). 
I get the following error saying component "env" in Framework "ess" is not found. Am I missing something?  I am new to MPI and any help you can offer is appreciated.

A requested component was not found, or was unable to be opened.  This
means that this component is either not installed or is unable to be
used on your system (e.g., sometimes this means that shared libraries
that the component requires are unable to be found/loaded).  Note that
Open MPI stopped checking at the first component that it did not find.

It looks like orte_init failed for some reason; your parallel process is
likely to abort.  There are many reasons that a parallel process can
fail during orte_init; some of which are due to configuration or
environment problems.  This failure appears to be an internal failure;
here's some additional information (which may only be relevant to an
Open MPI developer):

  orte_ess_base_open failed
