************************************************************************
Open MPI was unable to find threading support on your system. In the
near future, the OMPI development team is considering requiring
threading support for proper OMPI execution. This is in part because
we are not aware of any users that do not have thread support - so we
need you to e-mail us at ompi@ompi-mpi.org and let us know about this
problem.
To build this version of Open MPI without thread support, re-run
configure with the '--without-threads' option.
