[OMPI users] relocating an installation

Is it possible to use the environment or mpirun flags to run an OMPI that's been relocated from where it was configured/installed? (Say you've unpacked a system package that expects to be under /usr and want to run it from home without containers etc.) I thought that was possible, but I haven't f
