metapost not invoked? mpgraph.1 not created

[Patrick Gundlach <patrick@gundla.ch>]

Hi,

I use the following line to generate my pdf file:
texexec --pdf  rahmen.tex 

I have enabled write18 feature. I have put the following lines in 
rahmen.tex:

\setupcolors[state=start]
\runMPgraphicstrue
\runMPTEXgraphicstrue
\useMETAFUNformattrue
\startuseMPgraphic{Kreis}
  fill fullcircle scaled 200pt withcolor .625yellow ;
\stopuseMPgraphic
\useMPgraphic{Kreis}
\stoptext
\endinput

everything is just fine. After the texexec run, the pdf file includes the 
circle.

But when I have the follwoing tex file:

\setupcolors[state=start]
\runMPgraphicstrue
\runMPTEXgraphicstrue
\useMETAFUNformattrue

\starttext
\startuseMPgraphic{Text}
 draw btex \framed[width=fit,align=middle]{\input tufte \relax} etex ; 
  for i within currentpicture : 
   draw boundingbox i withpen pencircle scaled .2pt withcolor .625yellow ; 
  endfor ;
\stopuseMPgraphic
\useMPgraphic{Text}
\stoptext
\endinput

the mpgraph.1 will not be generated. (And an error appears in the pdf file 
"file mpgraph.1 unknown"). The mpgraph.log tells me:

This is MetaPost, Version 0.641 (Web2C 7.3.1) (mem=metafun 2001.2.17)  17 
FEB 2001 12:42
**&metafun mpgraph
(mpgraph.mp )

when I run 'mpost' and answer '&metafun mpgraph' when mpost outputs the two 
**, the log looks like this:

This is MetaPost, Version 0.641 (Web2C 7.3.1) (mem=metafun 2001.2.17)  17 

FEB 2001 12:42
**&metafun mpgraph
(mpgraph.mp
{randomseed:=2151}
write0 = `mpgraph.mpo'.

 [1] )
1 output file written: mpgraph.1

then the next texexec run (exactly as above) looks correct to me.

Why does texexec (?) not create the mpgraph.1 ?

btw: TeXExec 2.5, pdfeTeX, Version 3.14159-13d-2.1, ConTeXt  ver: 2001.1.9
