Why should you need the -devel package on the compute nodes? (It only contains the .h and .so files.) The RHEL and Fedora packages don't require it and work. [For an up-to-date OMPI, you can rebuild the package against the current tarball, at least after the chaos caused by RHEL 6.6 updating incompatibly to 1.8. Otherwise use the Fedora packaging, which is kept quite current.]
