I believe Hans Hagen said this around Sun, 10 Nov 2002:

I just wanted to jump in here as someone who has also had exactly this
error when using mp-graph. It still has not entirely gone away (I try to
run "mpost mpgraph", and I still get the above error... that points to
the problem not being in ConTeXt alone), but Hans suggested a patch for
me last week...

This indeed helped all graphs when running them through context, but the
underlying metapost problem remains when trying to run raw MP files with
'mpost'. FYI, I found the form.mp file Hans writes about in texmf/
metapost/context/mp-form.mp, at least in my TeXLive 7 install. (Hmm...
could this be a problem to TeXLive people?)

Good luck,
