I'm sorry I don't remember what the problems were. It was some
time ago (probably 14-16 months) when I was trying to use the
module. After spending a day or two on it, I switched to the
Delny module (which I had used in the past).

I do have Dlaunay triangulation working using VTK (which is
included in Enthought Python), but I haven't been able to
figure out how to extract the triangle list from the object
containing the resulting triangulation.  The object method that
people on the VTK mailing list tell me to call isn't available
in the Python binding.
