I thought anything different from f is true.
Anyway, when I make this change and create a cont-sys.tex
(where should this file be located in my $HOME/texmf tree?)
it doesn't work any better. Please keep in mind that in
certain cases, texexec launches the compilation of mpgraph.mp,
but not in this case. Hence, there might be another problem.

I am a bit reluctant to make these changes, since I will not
always be using texexec. I often use tex, latex and mpost alone.

I case it matters, below is the compilation of my example
with no prior mpgraph present:

But the copilation of 

\setupcolors[state=start]

\runMPgraphicstrue

\def\processword#1{\noindent\framed[frame=off,background=lions]{#1}\space}

\startuniqueMPgraphic{lions b}
  path p; p:=fullsquare

\stopuniqueMPgraphic

\defineoverlay[lions][\uniqueMPgraphic{lions b}]

\setupalign[broad,middle]

\processwords
{As you may know, \TeX's ambassador is a lion, while \METAFONT{} is
represented by a lioness. It is still unclear if they have a relationship,
but if so, and if a baby is born, may it enjoy \METAFUN.}

\stoptext                            

triggers metapost with exactly the same environment.

Even if I add \runMPgraphicstrue to my first example (previous posting),
there are still no mpgraph.1, etc. around.

When I did the tests, I took care to remove all auxiliary files
in both cases.
