metafun configuration problem?

[guravage@nlr.nl]

I am having problems running the self same context file on two similar TeX 
installations. I would greatly appreciate if anyone could offer any advice how 
I can track down and resolve the discrepancy.

First, here's a simple test file that exemplifies the problem:

% interface=en output=pdftex
\starttext
\startMPpage
draw btex foo etex
\stopMPpage
\stoptext

System A has tex-live-5 installed, and the latest version of context replacing 
that of the distribution. When I run `texexec life_cycle' the log shows just 
what you'd expect:

systems        : begin file foo at line 2
\openout1 = `foo-mpgraph.mp'.

Randomizer initialized to 807553133.
system(texexec --batch --output=dvips --mpformat=metafun --mptex --nomp --once 
foo-mpgraph)...executed.

 [MP to PDF foo-mpgraph.1] (./foo-mpgraph.1)
layout         : calculating backgrounds

System B has tex-live-5 installed, and the latest context installed in a 
separate texmf tree. The log of the same command run on B gives the first 
indication of a problem:

\openout1 = `foo-mpgraph.mp'.

Randomizer initialized to 794719257.
system(texexec --batch --output=dvips --mpformat=metafun --mptex --nomp --once 
foo-mpgraph)...executed.

figures        : figure foo-mpgraph can not be found
layout         : calculating backgrounds

So I ran the batch command explicitly on system A and all appears fine:

 TeXExec 2.5 - ConTeXt / PRAGMA ADE 1997-2001

       metapost to tex : foo-mpgraph
            executable : pdfetex
                format : cont-en
             inputfile : tmpgraph
                output : dvips
             interface : en
               options : once batch nomp
          current mode : all

This is pdfeTeX, Version 3.14159-14f-released-20000525-2.1 (Web2C 7.3.2x)

              run time : 1 seconds
       dvi to metapost : foo-mpgraph
              metapost : foo-mpgraph
                format : metafun
This is MetaPost, Version 0.641 (Web2C 7.3.2x)

Running the same command on system B dies prematurely with the error, "sh: 
mptotex  command not found."

TeXExec 2.5 - ConTeXt / PRAGMA ADE 1997-2001

       metapost to tex : foo-mpgraph
sh: mptotex: command not found

                format : metafun

The generated foo-mpgraph.mp files from both systems are identical with the 
exception of the ramdomseed assignment on line 3. Running metapost directly 
with the foo-mpgraph.mp on system A yields:

mpost foo-mpgraph.mp

The control sequence at the end of the top line
of your error message was never \def'ed. If you have
misspelled it (e.g., `\hobx'), type `I' and the correct
spelling (e.g., `I\hbox'). Otherwise just continue,
and I'll forget about whatever was undefined.

I've compared the texmf.cnf and cont-sys.tex files from both systems, but I 
don't any significant differences.

Both systems use the self same TeX and the latest context distributions - 
except that system B has a later version of pdftex, and system B has context 
and pdftex in a separate texmf tree.

As I said, I would appreciate any suggestions how I might track down and 
resolve this discrepancy.

Cheers,

Michael
