[O-MPI users] TCP problems with 1.0rc4

[Mike Houston]

We can't seem to run across TCP.  We did a default 'configure'.  Shared 
memory seems to work, but trying tcp give us:

[0,1,1][btl_tcp_endpoint.c:557:mca_btl_tcp_endpoint_complete_connect] 
connect() failed with errno=113

I'm assuming that the tcp backend is the most thoroughly tested, so I 
thought I'd ask in case we are doing something silly.  The above is 
caused when running the OSU NBCL mpi_bandwidth test.

Thanks!
