[OS X TeX] pgf and stack overflow

When trying to run an example from the pgf graphics package I get:
This is pdfeTeX, Version 3.141592-1.30.4-2.2 (Web2C 7.5.5)
\write18 enabled.
entering extended mode
LaTeX2e <2003/12/01>
! TeX capacity exceeded, sorry [input stack size=5000].

I am trying to run the example on the cover of the TikZ and pgf  
manual (version 1.01):

\begin{tikzpicture}[grow cyclic]
\tikzstyle{level 1}=[sibling angle=120]
\tikzstyle{level 2}=[sibling angle=60]
\tikzstyle{level 3}=[sibling angle=30]
\tikzstyle{every node}=[fill]
\tikzstyle{edge from parent}=[snake=expanding waves,segment  
length=1mm,segment angle=10,draw]
\tikz [grow cyclic,shape=circle,very thick,level  
\node {} child [color=\A] foreach \A in {red,green,blue}
{ node {} child [color=\A!50!\B] foreach \B in {red,green,blue}
{ node {} child [color=\A!50!\B!50!\C] foreach \C in {black,gray,white}
{ node {} }

How do I go about increasing the TeX stack capacity---or is something  
else wrong? I was able to run all the other examples I tried in the  
manual. I am using MacOSX 10.4.4 with TeXShop 2.09.
Thanks for any help, ...Peter
