Yes, in that case (though knem was meant to be used and it's annoying that configure doesn't abort if it doesn't find something you've explicitly asked for, and I didn't immediately need it). However, I got the same for at least mpi_abort_print_stack with that parameter set. This didn't happen with OMPI 1.6 and there's no obvious way to turn it off.
