Hi Luigi,

As I said, this example does not produce a PDF file for me.  I will attach the output.

Undefined control sequence ...
...and it points to \showfontkerns

In previous attempts to load a font file directly, I used a command structures something like
     [file:FreeSerif.otf*default],
but these never worked for me either,
and you seem to be using some other method. 
How should one load the file for this example?

You didn't answer the question: to investigate this behaviour, must I install a second, newer version of context, or can I use the disro version?  What is the reason for installing the latest version of ConTeXt?  Is this \showfontkerns only in versions newer than 2012.05.30 11:26 MKIV ?

This \showfontkerns may be interesting to me, generally.  (So I have a further incentive to get this going!)

Quick how-to
$>##  install latest minimals under  /opt/luatex/standalone-new
$>## and run the test
$>mkdir -p /opt/luatex/standalone-new
$>cd /opt/luatex/standalone-new
$>wget http://minimals.contextgarden.net/setup/first-setup.sh
$>bash /first-setup.sh --modules=simplefonts
$>## wait a little
$>cd tex
$>source setuptex
$>## ok we shoudl have context mkiv now
$>context --version
$>cd texmf-project
$>mkdir fonts &&  cd fonts
$>wget http://ftp.gnu.org/gnu/freefont/freefont-src-20120503.zip
$>unzip freefont-src-20120503.zip
$>cd freefont-20120503
$>mv *.ttf  ../
$>cd ..
$>mtxrun --script font --reload
$>## let's see if they are installed
$>mtxrun --script fonts --list --all|grep free
$>cd ..
$>## put the test.tex here
$>context test.tex

vertical bars are the result of \showkerns

could be.
