Comment (by dledford):

 Environment modules comes into play *any* time openmpi is used.  Whether
 building or running an application.  You can't just run an mpi app, it
 must be started by the mpi runtime (which isn't available without the
 environment module being loaded).  And you can't just link against mpi
 libraries, they are added to your app by mpicc (or one of the other
 compiler wrappers).  Anyone attempting to make a generic shared library
 that links against mpi libraries and then is used by a subsequent
 application without knowing about the mpi stack is a non-starter.

 As for more than one version, you can never have more than one version in
 a repo at a time, but you have all released versions archived via koji and
 have access to them, and you have the option to tell yum to just install
 new openmpi versions instead of upgrading.  The support for multiple
 versions exists in the package, not in the infrastructure, so it does take
 some work to get multiple versions installed, but once done, it works just
 fine.
