Generating LaTeX output

[Ernesto Trajano de Lima]

Hello,

I'm trying to generate LaTeX output from a .ly file. As far as I could 
understand I'm supposed to use lilypond-book. This is the output I get:

$ lilypond-book -f latex appassionata.ly

lilypond-book (GNU LilyPond) 2.1.30
Reading appassionata.ly...
Dissecting...
Traceback (most recent call last):
  File "/sw/bin/lilypond-book", line 941, in ?
    main ()
  File "/sw/bin/lilypond-book", line 938, in main
    do_file (files[0])
  File "/sw/bin/lilypond-book", line 833, in do_file
    textwidth = get_latex_textwidth (source)
  File "/sw/bin/lilypond-book", line 713, in get_latex_textwidth
    preamble = source[:m.start (0)]
AttributeError: 'NoneType' object has no attribute 'start'

I'm using Mac OS X 10.3.3 and lilypond 2.1.30. What am I doing wrong?

Cheers,
Ernesto.
