plot3d with clisp



I can build maxima with clisp, but:

bash-2.05$ clisp -M maxima-clisp.mem 

(...snip...)

(C1) plot3d(x+y,[x,-3,3],[y,-3,3]);

*** - FUNCALL: the function POLYGON-PTS is undefined
1. Break [1]> :q
(C2) load("plot.lisp");
;; Loading file plot.lisp ...
;; Loading of file plot.lisp is finished.
(D2)                               plot.lisp
(C3) plot3d(x+y,[x,-3,3],[y,-3,3]);



     and everything appears all right. Looks (but I am not any lisp
xprt) a compilation (clisp-related) problem?

      In any case, this is not urgent for me (I use maxima for other
things), but maybe it is for the package.
