[vox-tech] can't open display with ssh2



I'm unable to forward X despite the fact that I used the -X option with
ssh and ForwardX11 is set to yes in ssh_config on the remote machine (on
both machines, actually).  I get the error message

Error: Can't open display:

which evidently means that ssh2 has failed to perform its usual magic in
setting up the display.  A wander through google has comforted me with the
realization that I am not alone in having this problem, although it has
not given me any answers.  Any idea what's happening?  I saw nothing
obviously amiss in the output of ssh -v, but will append the output below
in case others see problems I missed.
