Hi, 
thanks to you and Renaud; I changed my file to this:
...................................
\setupoutput[pdftex]
\runMPgraphicstrue
\useMPlibrary[txt]

\setuppapersize[S6][S6]
\setupcolors[state=start]

\startMPinclusions
numeric u; u=.8cm;
path AX; AX=(10u,0)--(0,0)--(0,10u);
\stopMPinclusions
\starttext
\startuseMPgraphic{dummy}
pickup pencircle scaled .8mm;
drawdblarrow AX withcolor green;
label.rt(textext("$3x^2+\pi$"), (5u,6u));
\stopuseMPgraphic

\placefigure[left]{bla.bla}{\useMPgraphic{dummy}}
\input dawkins
\stoptext
...................................

I get the same "unknown" in place of the label.
On computer one (my everyday machine) context is provided by TeX-Live, and
I made the same experiment with my computer two where context is installed
via TeTeX.
Same result on both!

I Think I have followed  normal installation procedures (enabling write18
etc.)
So I'm confused
Thanks for any more help!
