Hi Hans,
Do you have pstoedit installed ?
root@debian:/home/fab# apt-cache search pstoedit
libpstoedit0c2a - PostScript to editable vector graphics library (runtime
files)
root@debian:/home/fab#
I compile the file test.tex  with  context test.tex

Anyway, there is a new mechanism that doesn't depend on additional
programs:
% outlinetext   (text) transformations ;
% outlinetext.d (text) (draw options) transformations ;
% outlinetext.f (text) (fill options) transformations ;
% outlinetext.b (text) (draw options) (fill options) transformations ;
% outlinetext.r (text) (fill options) (draw options) transformations ;
\starttext
\startMPdefinitions
    let graphictext = new_graphictext ;
\stopMPdefinitions
\startMPpage
draw outlinetext.b
        ("\framed[align=normal]{\input{tufte}}")
        (withcolor .5white)
        (withcolor red withpen pencircle scaled 1/10)
        xsized 10cm ;
\stopMPpage
\startMPpage
draw outlinetext.r
        ("\framed[align=normal]{\input{tufte}}")
        (withcolor red withpen pencircle scaled 1/10)
        (withcolor .5white)
        xsized 10cm ;
\stopMPpage
\startMPpage
draw outlinetext.d
        ("\framed[align=normal]{\input{tufte}}")
        (withcolor .5white)
        xsized 10cm ;
\stopMPpage
\startMPpage
picture p ; p := outlinetext.p("PX") ;
for i within p :
        draw i withcolor red withpen pencircle scaled 1/10 ;
    endfor ;
\stopMPpage
\stoptext
