[luatex] MPlib + graphictext

[Troy Henderson]

I'm trying to use MetaFun's "graphictext" with LuaLaTeX + MPlib with the
following code:

% Begin code
\documentclass{standalone}
\usepackage{luamplib}
\mplibsetformat{metafun}
\begin{document}
   \begin{mplibcode}
      beginfig(0);
         graphictext "Fun" scaled 4 withdrawcolor blue withfillcolor
.5white withpen pencircle scaled 5pt;
      endfig;
      end
   \end{mplibcode}
\end{document}
% End code

However, I am getting the following error (perhaps because it cannot find
my installed pstoedit in /usr/local/bin).  I would appreciate assistance.

Thank you in advance,

Troy
