>From the output you supplied, it looks like you are running Open MPI v2.1.x.
Did you install Open MPI v2.1.x from source, and install it into the same directory that you had previously installed Open MPI v2.0.x? If so, the warnings you are seeing (not errors) are likely the fact that there are some Open MPI v2.0.x plugins left over in the Open MPI v2.1.x installation tree (installing version B of Open MPI over a previous installation of Open MPI version A does *not* remove all of version A's files). You should probably get a clean install of Open MPI v2.1.x, and the warnings will disappear.
