Comment #4 on issue 1780 by address@hidden: Scheme format functions  
with no destination parameter cause deprecation warnings in Guile V2
http://code.google.com/p/lilypond/issues/detail?id=1780

On a system with Guile V2, the call from titling-init.ly before your change  
caused Guile to signal a deprecation warning from (ice-9 format), before  
causing Lilypond to abort the compilation completely.

  \line {

    %% 2014 = em dash.

    #(ly:export
<<<< Before fix
      (format "Music engraving by LilyPond ~a~awww.lilypond.org"
====
      (format #f "Music engraving by LilyPond ~a~awww.lilypond.org"

       (lilypond-version)
       (ly:wide-char->utf-8 #x2014)
       ))
  }
}

Here's a log from firing up lily to compile a simple file before applying  
your patch. Thanks for your work so far in helping to trace this,  I'll add  
some more information shortly,

Cheers Ian
