mp file not compiling

[Aditya Mahajan <adityam@umich.edu>]

Hi,
  Is the mp support for btex...etex broken in the latest context 
(ConTeXt  ver: 2006.04.27 15:59) The following does not compile,

\starttext
\startMPpage
   label(btex This is a test etex, origin) ;
\stopMPpage
\stoptext

I get an error

! Unable to make mpx file.
l.123 label(btex
                   This is a test etex

Even an mp file

beginfig(1)
   label(btex hello world etex, origin) ;
endfig
                                        end;

with texexec --mptex gives the same error message.

Can somebody confirm this? Or is something broken at my end?

Aditya
