Can you try adding the following param:
OMPI_MCA_pml=cm
and report the results?
Thanks,
Galen

There is a known issue on BProc 4 w.r.t. pty support. Open MPI by
default will try to use ptys for I/O forwarding but will revert to
pipes if ptys are not available.
You can "safely" ignore the pty warnings, or you may want to rerun
configure and add:
--disable-pty-support
I say "safely"
