Dear ConTeXt folks,


using the following minimal example

        \usemodule[graph]
        
        \starttext
        \startMPcode
        draw unitsquare scaled 1cm;
        \stopMPcode
        \stoptext

causes the following error.

        $ context graph

Removing `\usemodule[graph]` make the example work. The used terminal(?)
and use of `mp-spec.mpii` looks suspicious.

Using the ConTeXt version in Debian Sid/unstable the example works.
