Michael, in this case, you can mpirun --mca oob ^ud ... in order to blacklist the oob/ud component.
an alternative is to add oob = ^ud in /.../etc/openmpi-mca-params.conf If Open MPI is installed on a local filesystem, then this setting can be node specific. That being said, the error suggest mca_oob_ud.so is a module from a previous install, Open MPI was not built on the system it is running, or libibverbs.so.1 has been removed after Open MPI was built. So I do encourage you to take a step back, and think if you can find a better solution for your site.
