brace mismatch in init.ly

[Matthijs Frankena]

Hello,

Having finally installed Fedora Core 2 and everything to get going with 
Lilypond, I run into the following:

----------
$ lilypond DeinHerz.ly
GNU LilyPond 2.4.1
Processing `DeinHerz.ly'
Ontleden...

/usr/share/lilypond/2.4.1/ly/init.ly:28:5: fout: syntax error, 
unexpected STRING, expecting '=':
            
           "\n"

/usr/share/lilypond/2.4.1/ly/init.ly:28:8: fout: onbekende ontsnapte 
string: `\n':
           "\n
              "

/usr/share/lilypond/2.4.1/ly/init.ly:29:62: waarschuwing: Haakjes paren 
niet:
           input-file-name ": old relative compatibility was not use
                                                                    d."

fout: bestanden gefaald: DeinHerz.ly
----------

Apparently there's some mismatch in braces in this section in init.ly:
------------
\maininput
%% there is a problem at the end of the input file

%%
%% Above and below comments compensate for the parser's look-ahead.
%%

#(if (and (ly:get-option 'old-relative)
     (defined? 'input-file-name)
     (not (ly:get-option 'old-relative-used)))
 (ly:warn (string-append
       "\n"
       input-file-name ": old relative compatibility was not used."
   )))%% there is a problem at the end of the input file
-----------------

Can anyone tell me where to add/delete a brace, or whether the fault 
lies in my input file?

TIA,

Matthijs
