[pdftex] Problem with pdflatex ...

[Damien SAUVERON]

Hello,

    I want to compile the following example with pdflatex but the
following error appears.
    Could you help me please ?
    Thanks

Damien SAUVERON

The example :
\documentclass[a4,portrait]{seminar}

\usepackage{pstcol} % To use the standard `color' package with Seminar
\usepackage{semcolor}

\input{seminar.bug}

\usepackage{pst-grad}

\definecolor{Gold}{rgb}{1.,0.84,0.}
\slideframe[\psset{fillstyle=gradient,gradmidpoint=0.5,
                   gradbegin=Gold,gradend=yellow}]{scplain}

\begin{document}

\begin{slide*}
  My slide with a nice gradient background.
\end{slide*}

\end{document}


The error:
