What do you refer to by "packaged" octave ?

What didin't work with regards to the image toolbox?

Regarding the blank AquaTerm image, a bug report has been filed with Gnuplot.

The Gnuplot provided by MacPorts includes a Qt terminal.  You may be happier 
with qt than with x11.

        graphics_toolkit gnuplot
        setenv GNUTERM qt
        img = uint8 (round (255 * rand (5,4,3)));
        image (img)
