You surely do.

Also, make sure the environment, in particular PATH and LD_LIBRARY_PATH
is propagated to the compute nodes.
Not doing that is a common cause of trouble.
OpenMPI needs PATH and LD_LIBRARY_PATH at runtime also.

I hope this helps,

I haven't used Rocks Clusters in a while,

suggestions with a grain of salt, and check them out
before committing to them

Which --prefix did you use when you configured Open MPI?
My suggestion is that you don't use "/export/apps" as a prefix
(and this goes to any application that you install).
but instead use a /share/apps subdirectory, something like:

--prefix=/share/apps/openmpi-1.8.4_gcc-4.9.2

This is because /export/apps is just a mount point on the
frontend/head node, whereas /share/apps is a mount point
across all nodes in the cluster (and, IIRR, a soft link on the
head node).

My recollection is that the Rocks documentation was obscure
about this, not making clear the difference between
/export/apps and /share/apps.

Issuing the Rocks commands:
"tentakel 'ls -d /export/apps'"
"tentakel 'ls -d /share/apps'"
may show something useful.
