ppctex + pstricks on texlive2009

["Patrice Mégret" <Patrice.Megret@umons.ac.be>]

Dear all,

I have installed texlive2009 in place of texlive2007 and I can no longer compile programmes combining pstricks and ppchtex.

The following example gives me an error (it is still working on texlive2007 on another pc)

\documentclass{article}
\usepackage{pstricks}
\usepackage[pstricks]{m-ch-en}

\listfiles
\begin{document}
\chemical{O_2}
\startchemical
\chemical[SIX,B1..6,R1..6,RZ1..3][CH_3,CH_3,OH]
\stopchemical
\end{document}


! Undefined control sequence.
l.4441 \writestatus
                   {loading}{ConTeXt System Macros / General}
?
! Emergency stop.
l.4441 \writestatus
                   {loading}{ConTeXt System Macros / General}
End of file on the terminal!

I have no idea how to cope with that error.



Any help is welcome.


Best regards,

Patrice
