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.

                   ;

)

!mplib          : mp terminal: [1]
