Happy for *them*, at least.  ;-)

Ok, that's good.

Ok.  We're still somewhat at a loss here, because we don't have any NetBSD to test on.  :-(  We're happy to provide any help that we can, and just like you, we'd love to see this problem resolved -- but NetBSD still isn't on any of our core competency lists.  :-(

FWIW, we might want to move this discussion to the devel at open-mpi.org mailing list...
