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. --
