I’m using a build of OpenMPI provided by a third party.

    Gary,
    
    
    one option (as mentioned in the error message) is to configure Open MPI 
    with --enable-orterun-prefix-by-default.
    
    this will force the build process to use rpath, so you do not have to 
    set LD_LIBRARY_PATH
    
    this is the easiest option, but cannot be used if you plan to relocate 
    the Open MPI installation directory.
    
    
    an other option is to use a wrapper for orted.
    
    mpirun --mca orte_launch_agent /.../myorted ...
    
    where myorted is a script that looks like
    
    #!/bin/sh
    
    export LD_LIBRARY_PATH=...
    
    exec /.../bin/orted "$@"
    
    
    you can make this setting system-wide by adding the following line to 
    /.../etc/openmpi-mca-params.conf
    
    orte_launch_agent = /.../myorted
    
    
    Cheers,
    
    
    Gilles
