What version of Fedora are you using, and on what architecture (i.e. i686
or x86_64)? As far as I can see, the last Fedora distro to use
openmpi-libs was Fedora 11, which is rather old and unsupported.

Current versions of Fedora use the "module" command to load the proper
environment for Open MPI. On a 64bit machine, e.g., one would run
"module load openmpi-x86_64" to get all the env variables properly set.
But I don't know what Fedora version that started with.
