metapost doesn't understand the &latex line, tex does. So what
happens what you do "tex --parse-first-line mpxerr.tex"? I'm betting
this:
infovore:/tmp$ tex --parse-first-line mpxerr.tex
This is TeXk, Version 3.141592 (Web2C 7.5.3)
%&-line parsing enabled.
---! /usr/local/share/texmf/web2c/etex/latex.fmt was written by etex
(Fatal format file error; I'm stymied)
though likely without the helpful '---!' message if you're using older
binaries.
We probably ought to do is change 'makempx' to get the %& line out and
use the command it finds there. Something like this might do:

The sed expression does the following: Check if the first line starts
with %& and matches %&<whitespace>NAME<...>, in which case we set TEX
to 'NAME --parse-first-line' (there might be more options that we
didn't copy out).
If TEX is still empty after that, use the default value.
makempx.c will have to be updated as well. :-(
