I think Ethan's point above is important. We went through great lengths
earlier this year to make Open MPI STL agnostic so an application can
choose which STL it would like to link in. In other words there really
should be no need to tie (link) libmpi to a specific STL thus allowing
the application to do the actual linking to the STL it prefers.
