Hi Qiang This error message usually indicates that you have more than one Open MPI installation around, and that the backend nodes are picking up a different version than mpirun is using. Check to make sure that you have a consistent version across all the nodes.
I also noted you were building with --enable-threads. As you've probably seen on our discussion lists, remember that Open MPI isn't really thread safe yet. I don't think that is the problem here, but wanted to be sure you were aware of the potential for problems.
