Beamer example (typeset second screen) does not compile

Question

I'm trying to use the [typeset second] option in a beamer frame as specified by the Beamer User Guide. When I compile with that option, I receive the error Undefined control sequence \end{frame}

I tried compiling the sample from the guide and received the same error. This issue has been reported occasionally but I haven't found a solution. Full code listing (copied directly from the guide):

\documentclass{beamer}
\usepackage{pgfpages}
\setbeameroption{second mode text on second screen}
\begin{document}
\begin{frame}[typeset second]
  This text is shown on the left and on the right.
  \only<second>{This text is only shown on the right.}
  \only<second:0>{This text is only shown on the left.}
\end{frame}
\begin{frame}
  This text is shown on the left. The right shows the same as for the
  previous frame.
\end{frame}
\begin{frame}[typeset second]
  \alt<second>{The \string\alt command is useful for second
    mode. Let’s show the table of contents, here: \tableofcontents}
  {Here comes some normal text for the first slide.}
\end{frame}
\end{document}

Answer 1

The example code compiled as expected in my system, so perhaps Andre was using an outdated TeX Live system. This was confirmed and the problem was solved, as can be seen in this quote taken from his comment:

Yes, I was using TeXLive 2007, but have now upgraded to the 2010 version. It compiles correctly.
