Hello, Werner:
Have you tried some diagnostic tests, such as trying to get the PDF
output via DVIPS? I suspect that you are, in fact, more knowledgeable
and experience with ConTeXt than I am, but for what it is worth you may
want to look at:
* \setupoutput[dvips,acrobat] (SEE: _Context-The Manual_ (Hans Hagen;
English, page 24))
* \showbodyfont[Options] (SEE: _Not-so-short Intro to ConTeXt (_J.
Ataz-Lopez;English, page 114))
* $ MTXRUN (mtxrun is the _ConTeXt TDS Runner Tool_) command from a
terminal window it has has a large number of options for finding the
fonts installed, and for querying their characteristics (SEE: _Fonts out
of ConTeXt _(Hans Hagen, pg 52 and ff))
