Now I have the `/undefined in hello' error again:

\documentclass{minimal}
\usepackage{pstricks}

\begin{document}
\pstVerb{SDict begin /hello (hello!!!) def end}
\pstVerb{SDict begin hello print end}
foo
\clearpage
\pstVerb{SDict begin hello print end}
foo
\clearpage
\pstVerb{SDict begin /hello (good bye!!!) def end}
\pstVerb{SDict begin hello print end}
foo
\clearpage
\pstVerb{SDict begin hello print end}
foo
\end{document}
