btex-etex

[Jiri Polcar <polcar@physics.muni.cz>]

    Hallo,

my ConTeXt ignore btex-etex command. It works as the btex-etex command
is empty. No text on output. Simple example:

    \starttext

    \startuseMPgraphic{test}
      picture p; p := btex TEST etex scaled 5cm;
      draw p; 
    \stopuseMPgraphic

    \useMPgraphic{test}

    \stoptext

On output is only page number. In the 'mpgraph.mp' is (if a skip some
definitions):

    ResetTextAreas ;
    SaveTextAreas ;
    ResetTextAreas ;
    if unknown context_core : input mp-core.mp ;
    fi ;
    local_multi_par_area:=false;
    ;;
    verbatimtex \global \loadfontfileoncetrue  etex;
    let mprunend = end ;
    beginfig(1);
    picture p;
    p := btex TEST etex
    scaled 5cm;
    draw p;
    endfig;
    let end = mprunend ;
    end.

If a extract a part with 

    beginfig(1);
    picture p;
    p :=  btex TEST etex;
    draw p;
    endfig;
    end.

and proccess it with mpost it works good. My ConTeXt comes from Fedora
Core 3 distribution. Any suggestion how to solve it?
