Draw demo.



I got the draw demo to execute  in wxmaxima on WinXP with no problems.

My friend tried to do it in Linux. He had this problem. Can you tell 
what is wrong?
This was his first attempt at Maxima.  He is going to install  WinXP 
maxima to try
draw while he gets this problem solved.

=====

<>I spent several hours today to get the right version of maxima running 
on my Debian Linux.
The version of the distribution was too old. I thought I had all 
required parts ready, but
"load(draw)$" says:load failed.  I also replaced gnuplot with version 
4.2 which was also
not so easy because of the dependencies.<>
 
Furthermore, the line

  vect1: makeset(vf(x,y,z), [x,y,z], points1)$

gives:

  Function makeset expects a list or a set, instead found cartesian product.
