Hello,

the code works in cvs Maxima, but not in Maxima 5.21. If you don't want 
to wait for Maxima 5.22, just download the latest versions of files 
"draw.lisp" and "worldmap.mac" from

http://maxima.cvs.sourceforge.net/viewvc/maxima/maxima/share/draw/

and copy them into your "share/draw" folder. After that, execute

load("draw");

and run the script again.

PD: Even if you don't need package worlmap, update it since some changes 
in draw.lisp are related to worldmap. In doing so, you will override 
possible incompatibilities.
