__gnuplot_replot__ fails in octave-2.1.69

Whenever I try to use the routine __gnuplot_replot__, I get an error:

  octave:1> __gnuplot_replot__();
  error: plot: can only plot in 2 or 3 dimensions
  octave:1> 

I'm running on a dual processor G5 Mac with OS X 10.3.9. Octave-2.1.69 was
built from source with gcc-3.3 (Apple's version) and g77-3.4.2. Everything
else seems to be working correctly.

I'm attempting to use Dmitri Sergatov's new plot routines (print.m,
legend.m, etc.) for octave-forge for octave-2.9.1. The old plot routines,
for example, replot; work correctly, but give warning messages when graw or
gset are used.
