[pstricks] Problems with \psbrace again

[Alan Ristow]

I am having trouble with \psbrace again. When I run the example from the 
pstricks-add docs:

\documentclass{article}
\usepackage{pstricks}
\usepackage{pstricks-add}
\listfiles
\begin{document}
\begin{pspicture}(4,4)
   \psgrid[subgriddiv=0,griddots=10]
   \pnode(0,0){A}
   \pnode(4,4){B}
   \psbrace[linecolor=red,ref=lC](A)(B){Text I}
   \psbrace*[linecolor=blue,ref=lC](3,4)(0,1){Text II}
   \psbrace[fillcolor=white](3,0)(3,4){III}
\end{pspicture}
\end{document}

I get the following error:

ERROR: Undefined control sequence.

l.10 ...sbrace[linecolor=red,ref=lC](A)(B){Text I}
