Hallo.
I tried mtxrun --script mptopdf chart08.1 but I've got the following error.
This is pdfTeX, Version 3.1415926-1.40.11 (TeX Live 2010)
 \write18 enabled.
entering extended mode
[MP to PDF]
(./charts08.1{/home/qasar/programy/context_stable/tex/texmf/fonts/m
ap/pdftex/plain/pdftex.map}) [1]
!pdfTeX error: pdftex (file lmmi9): Font lmmi9 at 600 not found
 ==> Fatal error occurred, no output PDF file produced!
I have tried to compile the following example:
beginfig(1);
draw btex $x+1=2$ etex;
endfig;
end.
It works fine with TeX Live 2010/TLContrib, but fails in minimals
(nearly-latest version of ConTeXt).
To me this seems as if mptopdf was trying to run plain pdfTeX instead
of ConTeXt [or I have no idea what]. It then only reads pdftex.map
which certainly lacks the information about lmmi font. But I wonder
why it only reads from pdftex.map ... I could fix pdftex.map, but I
would like to figure out what exactly is going on ...
Just some more information ... Looking into the filename.1 makes me
very suspicious:

What exactly does "begindraw" do in EPS file? Adding ec-lmr12 and
lmmi12 into pdftex.map got rid of the error, but didn't generate any
valid output (it created an empty pdf). What mptopdf run on filename.1
does is basically
    pdftex -fmt=mptopdf -progname=context \\relax mathmp.1
(maybe I'm wrong; but it behaved exactly like that), but I didn't
manage to get any sensible output out of that.
