can't plot in Octave on my Mac, but gnuplot and Aqua are working

[Jonathan Kane]

Hi,
   I installed Aquaterm 1.0.1 and gnuplot 4.0 and I can make plots with gnuplot, so I think I installed them correctly.  I installed Octave and set the following variables in .bashrc:
**
export AQUATERM_REPORT_TIMING=1
export AQUATERM_PATH=/Applications/AquaTerm.app
export PATH=$PATH:/usr/local/bin
export GNUTERMAPP=/Applications/AquaTerm.app
export GNUTERM=aqua
**

When I start Octave up, I get the following error:

**
error: couldn't link module /usr/local/libexec/octave/2.9.9/site/oct/i386-apple-darwin8.9.1/octave-forge/__imagemagick__.oct
error: evaluating argument list element number 2
error: near line 1 of file `/usr/local/share/octave/2.9.9/site/m/octave-forge/image/PKG_ADD'
error: source: error sourcing file `/usr/local/share/octave/2.9.9/site/m/octave-forge/image/PKG_ADD'
error: near line 11 of file `/usr/local/share/octave/2.9.9/m/startup/octaverc'
**

Next, when I type a simple
 Matlab-like plotting command I get the following errors:

**
octave:1> sombrero(25)
parse error near line 46 of file /usr/local/share/octave/2.9.9/m/plot/mesh.m

  syntax error

>>>       __gnuplot_set__ noparametric;
                                     ^

error: `mesh' undefined near line 45 column 7
error: evaluating if command near line 40, column 5
error: evaluating if command near line 39, column 3
error: called from `sombrero' in file `/usr/local/share/octave/2.9.9/m/plot/sombrero.m'
**


Can anyone tell me what's going on?  Please help!  Thanks!!
