? I don't see a $GNUPLOT at or near line 229 in any version.
what does line 229 look like?

can you try using the latest CVS version?

before you start the GRASS from a terminal shell, or placed in
.grass.bashrc have you set  (assuming you use Bash and not Csh)

GRASS_GNUPLOT=/sw/wherever/gnuplot/is/gnuplot
export GRASS_GNUPLOT

?
