Is there a way to fix a compability issue with beamer?

Question

I compile a beamer presentation on my Mac, and everything works well, I get what I expect.

However, when I try it on a linux machine, I get the following error:

! Missing control sequence inserted.
<inserted text>
                \inaccessible
l.305 \end{frame}

Here is the frame around that line (i.e. that ends in line 305):

 \begin{frame}
 \frametitle{Probabilistic Grammars}

 \textcolor{blue}{We treat them}

 \begin{equation}
    p
 \end{equation}

 \begin{itemize}
 \item defined over a support 
 \end{itemize}

 \textcolor{mygreen}{Example}
 \end{frame}

Any idea what could be the problem?

Answer 1

Put \listfiles and \batchmode into the preamble of your document, run pdflatex or whatever and then compare the file list which can be found at the end of the logfile.
