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_[hidden] mailing list...
