metapost not invoked? mpgraph.1 not created

i've just compiled a new binary -> same problem.

This is pdfeTeX, Version 3.14159-13h-pretest-20010126-2.1 (Web2C 7.3.3.1)
I have tested another linux binary (precompiled) from tanh 
website (0.14f)

'nothing' :-) no mpgraph.1 generated. When I only declare 
\runMPgraphicstrue and not \runMPTEXgraphicstrue metapost tells 
me:

--------------------------------------

[...]
-----------------------------------------

Just to make things clear:
this is a sample file that gives me headaches :-) (I have 
removed the \framed[....]{...} stuff to make sure that there is 
no problem here)

% also tried with % removed
%\runMPgraphicstrue
%\runMPTEXgraphicstrue
%\useMETAFUNformattrue

\starttext
\startuseMPgraphic{Text}
 draw btex Hello world etex ; 
\stopuseMPgraphic
\useMPgraphic{Text}
\stoptext

------------------------------------

I think that the line with btex--etex is problematic.
the mpgraph.log file has no error messages:
 This is MetaPost, Version 0.641 (Web2C 7.3.1) (mem=metafun 2001.2.19)  19 FEB 2001 13:00
**&metafun mpgraph
(mpgraph.mp )

There is just *no* output. The same(?) mpost run, with exactly the 
words '&metafun mpgraph' typed by hand gives me an errorfree 
output:

This is MetaPost, Version 0.641 (Web2C 7.3.1) (mem=metafun 2001.2.19)  19 FEB 2001 13:00
**&metafun mpgraph
(mpgraph.mp
{randomseed:=2508}
write0 = `mpgraph.mpo'.

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

When I try the test.tex mentioned in the metafun (beta) manual, 
the output file mpgraph.1 is generated.

\starttext 
\setupcolors[state=start] 
\startMPpage colorcircle(10cm,red,green,blue) ;
\stopMPpage \stoptext

-------------------------------
some more questions:

* is there a problem only having a cont-en.efmt (no pdftex 
version, only pdfetex)?

* mptopdf: There is a perl script  with this name 
which is in my $PATH  
(unix). There is also a mptopdf.efmt. Is this correct?

I have no idea where to look for more hints on this issue.
