How about following makempx commands by hand that is,
mpto useemp.mp
This should strip out everything between btex ... etex into some tex

mpto useemp.mp temp.tex
Any non-existing filename instead of temp will do. Then do,
latex temp.tex
dvitomp temp.mp useemp.mpx
and if all of these work without any error, do
mpost useemp
If possible, use Context to create the graphics, i.e.
texexec --mptex useemp.mp
to get mps files (.1, .2, etc) or
texexec --mpgraphic useemp.mp

If however, you need to stick to latex for some reason, you need to

Educated guess: the 'embedded' latex never gets to see \documentclass

(In case you are wondering: the \end{document} is only there because

In the same directory as qdftools.mp, I have a file useemp.tex. Note
that I am using the emp package.
\documentclass{article}
\usepackage{amsmath}
\usepackage{emp,ifpdf}
\ifpdf
\DeclareGraphicsRule{*}{mps}{*}{}
\fi
\setlength{\unitlength}{1cm}
\begin{document}
Now is the time for all good men to come to the aid of their country.
\empprelude{input qdftools}
\begin{empfile}
\begin{empdef}[david](4,4)
numeric u; 10u=3in;
gridfivefive;
xyaxesfivefive;
\end{empdef}
\end{empfile}
\immediate\write18{mpost \jobname}
\empuse{david}
Now is the time for all good men to come to the aid of their country.
\end{document}
Now, here is what I fail to understand. If I compile useemp.tex with:
pdflatex --shell-escape useemp
Then all is well. I get a nice pdf file.
However, if I change one line in the file useemp.tex, namely
\immediate\write18{mpost \jobname}
to:
\immediate\write18{mpost -tex=latex \jobname}
Then if I remove the file qdftools.mpx and compile useemp.tex with:
pdflatex --shell-escape useemp
Then I get:

Can anyone tell how to work around this problem? I know Context has
much better support for labels, but I need to write this in Latex for
our online testing system. http://scinux.redwoods.edu/cgi-bin/
online_s06/testing.cgi/
I have faced this problem in the past, but was never sure why it
occured or how to rectify it. Try the command
mpost --tex=latex useemp.mp
on your shell. Do you get the same error message as before (you
should). Now try,
makempx --tex=latex useemp.mp useemp.mpx
Does this create an mpx file? If it does, then atleast a workaround
for the problem is to have
\immediate\write18{makempx --tex=latex \jobname.mp \jobname.mpx}
before
\immediate\write18{mpost --tex=latex \jobname}.
If makempx fails, look at the output of
makempx --verbose --tex=latex useemp.mp useemp.mpx
What do you get?
