[ncl-install] Ask for help: a problem about running NCL

[Mary Haley]

This is likely because you don't have an X11 server running.

The "gsun01n" example tries to send its graphical output to an X11 window,
which requires that you have a server running.

Try running a different example, and use a special flag to send the output
to a PNG file:

ng4ex xy01n -clean -W png

This should create a xy01n.png file.

X11 is a useful output format when you are debugging a graphical script, so
I recommend trying to install X11.  See this page for some details:
