Plotting with Maxima?



I used CLISP to get Maxima working for Darwin. It works fine, except for the
fact that I can't use plotting features.

For instance,

(C1) plot2d(sin(x), [x,-5,5]);
zsh: command not found: omplotdata
(D1)

I wonder what I have to do in order to get it working. I have XFree 4.0.2
and tclsh8.3

Thanks in advance,
Lizardo.
