bug?

[David Bobroff]

When using lilypond-book recently with the current CVS (ChangLog 1.986)
I've been getting this error at the LaTeX stage:

! Undefined control sequence.
l.2 \preLilypondExample

This short input file produces this error on my system [RedHat 9.0,
Lilypond 1.7.21 from CVS]

%%%%%%%%%%%%%%%%%%%%%%

\documentclass{article}
\begin{document}
\begin{center]
\Huge{A "C" scale}
\end{center}

\begin{lilypond}
\score {
    \notes \relative c { 
        c4 d e f g a b c
    }
    \paper { }
}
\end{lilypond}

\end{document}

%%%%%%%%%%%%%%%%%%%%%%

Also, the *.latex file generated by lilypond-book contains only this:


%%%%%%%%%%%%%%%%%%%%%%

{\parindent 0pt
\preLilypondExample
\input lily-86501838.tex
\postLilypondExample}

%%%%%%%%%%%%%%%%%%%%%%

Have I found a bug?
