[OS X TeX] Beamer problem in MacTeX

[Red Roo]

What works for: 
\documentclass{beamer}

no longer seems to work for beamer in article mode (generally used to produce handouts) using:
\documentclass{article}
\usepackage[envcountsect]{beamerarticle}

The offending tex involves the beamer thm env: 
\begin{example} 
 Delk and Fillenbaum experiment (1965)
 \includegraphics[width=4in]{memColor1.pdf}
\end{example}

and produces the complaint:

! Undefined control sequence.
\@begintheorem ->\beamer at storeaction 
                                     \beamer at origbegintheorem 
l.239 		 D
          elk and Fillenbaum experiment (1965)
---------

This worked with earlier versions of MacTeX/TeXShop and I couldn't find only discussion of this problem in Beamer fora on the web. It therefore looks like a MacTeX2008 problem, but it's not clear how. 

Has anyone else seen this problem?
