Hi Troy,
I don't have the graph.mp file, but I have seen similar errors here. I guess if you change the lines into
Gmargin.low:=-.07; Gmargin.high:=1.07;
things work again. Sorry, I can't remember the reason why equations cause trouble in mplib. But I'm quite sure that this is only an incompatibility and not a bug.
see http://archive.contextgarden.net/message/20091107.123912.3010813e.en.html for details. I will do the same :)
Best wishes, Peter

The following example produces expected output with MKII (texexec) but fails the compilation process with MKIV (context).
\startuseMPgraphic{foo} input graph; path p; gdata("data.d", $, augment.p($1,$2);); draw begingraph(4in,2.5in); gdraw p; endgraph; \stopuseMPgraphic \starttext \useMPgraphic{foo} \stoptext
The data stored in data.d is as follows: 0 0 1 1 2 4
When compiling with MKIV, the following error occurs:
!mplib : mp terminal: (/opt/context-minimals/tex/texmf/metapost/base/graph.mp ! Redundant equation. <to be read again> ; l.143 Gmargin.low=-.07; % bbox fraction for default ra...
