Subject: plotting to a postscript file no longer works.

Bug report for Octave 2.0.14 configured for alpha-suse-linux-gnu

Description:
-----------

I recently updated my linux version and the octave version.
I had scripts, like test.m, which I will include, that calculate
something and then create a postscript file containing a plot of the
results.  (I would make and view plots on the screen. This works
fine.) These scripts all worked.
The problem now comes when I try to create a *.ps file containing the
plot.  When I tried to view the *.ps file using ghostscript,
I saw the axes and labels, then a ghostscript message saying
"error: undefined in LT0 ...", .

	I sent the 'output_file.ps' to another machine
to its 'lpr' command, in case the problem was with ghostscript.
I just got a banner page out on the other machine.
