I can check that. Meanwhile, I think I have found a
significant clue ... I don't think X11 is even built on
the one system. There is a directory /usr/X11R6/bin,
but all it has in it is a few build tools like imake.
There are probably underlying libraries that haven't
even been built.

I'm not going to pursue it further. The system in
question, which has been a workhorse for the past 10
months or so, will be abandoned before long in favor of
the one that does allow connections.

No further responses necessary.

Thanks.
