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.
