I guess that you are running a True Color Xserver; such visual does
not support writing (modifying) the colormap. If you have more than
256 colors available, then probably you have a TRue Color xserver.
You can also check it typing `xrdb -symbols' an looking for string
"-DCLASS_". You can revert to a Pseudo Color visual by specifying
in your ~/.xserverrc (or whatever xserver configuration file your
redhat system uses)
exec /usr/X11R6/bin/X -dpi 100 -bpp 8
This should not be a problem for plplot if you dont change the colormap.
From the examples provided, only the "shade" demo tries to do it.
try running the demos one by one, eg, `p1', `p2', etc.

You can also check file `PLplot/pldef.m' and comment the lines
that exchange the background and foreground colors:
plscol0(15, 0, 0, 0);
plscol0(0, 255, 255, 255);
