(I don't understand the question, sorry...) I can compile all
maxima and run the tests without any error, but when I try to
plot3d something, I get that error. Now it is solved thanks to
Osman.

The problem is in src/plot.lisp, the definition of polygon
is in an

(eval-when ...)

loop, and this prevents its proper functioning under clisp.

This can be mended taking the def. of polygon out of that
eval-when.

Thanks for the concern,

	Pedro.
