PSTricks problem

[Herbert Gintis]

I just installed PSTricks on my laptop. When I compile the test program
that come with it (test-pst.tex), I get an error message from Acrobat
Distiller, saying there's an error in the ps file, then "OffendingCommand:
SDict". Any idea what this means?

The first commands that lead to this error are:

\begin{pspicture}(-1,0)(2,2)
   \begin{psclip}{\psdiamond(1.5,0.2)(2.0,0.5)}
     \Huge Scary Monsters
   \end{psclip}
\end{pspicture}
.
Best,
