[pstricks] pst-lens problem

[Dieter Grass]

Dear All,
I'm using Miktex and tried to include the lens effect of pst-lens. Therefore
I started with the example given in the book "PSTricks" by Herbert Voss:

-- snip --
\documentclass[11pt,draft]{book}

\usepackage{pstricks}
\usepackage{pst-lens}

\begin{document}
\def\Wishes{{%
    \rput[lb](0,0){%
      \Large\begin{minipage}{3cm}\centering
        \textbf{Alles Gute}\\\textbf{Jana},
        \\ fuer dieses neue Jahr\\\Huge 2006!
      \end{minipage}}}}

\begin{pspicture}(0,-1.5)(3,4)
\Wishes
\PstLens[LensMagnification=2,LensSize=2](2,2){\Wishes}
\end{pspicture}
\end{document}
-- snap --

But when I run latex I receive the following (error) messages in the log
file

and I'll forget about whatever was undefined.

I upgraded to the newest packages for pst-lens and xkeyval as I read that
otherwise problems with these packages can arise. Nevertheless the problems
remain and I didn't find or see any hint in the list archive to solve the
problem.

Any comment is welcomed. Thanks
