Most likely problem is version confusion as Fedora comes with a version of OMPI pre-installed. Check you LD_LIBRARY_PATH and PATH on both ends to ensure they are pointing at the same OMPI installation. Remember, interactive login typically uses a different shell startup then non-interactive job launch, so be sure that the latter is getting the right path.
Also, be sure you don't have a firewall running between the two computers. What version of OMPI are you trying to install?
