The issue is that openpty() is failing on the machine. I think /dev/ptmx and /dev/pts have to exist for pty support to work properly. We're having the same issue on Coyote, but not on Pink and Flash. As far as I can tell, those are the files / directories that are on the working systems but not coyote.
