Yes, but it has been mostly fixed in CVS.  Please see

http://www.math.utexas.edu/pipermail/maxima/2003/003591.html

and apply the patch given there or (better) fetch vect.mac from the
CVS archive. 

Prefix operators (like DIV) are still broken.  There's a fix

http://www.math.utexas.edu/pipermail/maxima/2003/003592.html

but it isn't in CVS yet.
