I need to make that error string be google-able -- I'll add it to the
faq. :-)

The problem is likely that you have multiple IP addresses, some of
which are not routable to each other (but fail OMPI's routability
assumptions). Check out these FAQ entries:

http://www.open-mpi.org/faq/?category=tcp#tcp-routability
http://www.open-mpi.org/faq/?category=tcp#tcp-selection

Does this help?
