I mereged your __DragonFly__ stuff into my patch and applied it
against the NetBSD build.

Things are still running on NetBSD albeit with the temporary name
resolution issues. These come from a routine in opal/util/net.c

opal/util/net.c:opal_net_get_hostname()

and it is being called from:

orte/mca/oob/tcp/oob_tcp.c:mca_oob_tcp_parse_uri()

I've looked at these routines before, it was how I discovered
that the s_len was not being set, so I'll have another dig
around and see if I can see why the temporary errors occur, and,
indeed, if they are actually temporary.

The contents of the NetBSD patches directory I have been using,
including your stuff, is now here:
