"errors" when running plot

Umm, no ... why would I have X11 running on a Linux server, located in 
somebody's closet, basically? (Oh the culture shock!)  Relying on X11 for 
things besides windowing seems bad to me.

Thanks for working with me Ben!  Hopefully this is useful to someone besides 
me....

One thing is that if you are running a server, superfluous messages like about 
X11 not being set can really screw you up, and (at the very least) generate a 
lot of annoying email messages via cron.  So unless it really matters, they 
should be eliminated.  I slightly customized my gnuplot installation to get rid 
of a stupid warning about the fonts that they introduced with the last release.
