Oops, you are right! The documentation says that the old shape extension is
gone, and I verified that I  am no longer building it.  What happened is
that the shape directory was lying around from the 2.0.a9 build and I
accidentally ended including an older build of shape.gex  which does not
work with 2.0.1.oga.1 (extensions must be compiled for a given version of
grads).

Kevin: Please delete shape.gex from your gex/ directory and use the "draw"
command instead as Jennifer suggests.
