[NTG-context] Error under Ubuntu Lnux

[Alain Delmotte]

Hi!

I installed Ubuntu 9.10 (in a VMWare Player under Windows)

I also installed the minimals and TeXworks (in the ConTeXt tree).

I run setuptex, TeXworks but then I get an error.
Here information:

This is LuaTeX, Version beta-0.50.0-2009122419
\write18 enabled.
(/home/alain/Documents/context/premier.tex
ConTeXt  ver: 2010.03.30 18:56 MKIV  fmt: 2010.4.1  int: english/english

For a simple source (created under Linux), here the source and the error:
