lilypond-book (LilyPond 2.6.3-1)

[Rembrandt Wolpert]

OSX 10.4.2
Lilypond 2.6.3-1 (dmg-download)

I am new to lilypond, and am trying to use lilypond-book, but get:

lilypond-book ~/Desktop/silly.ly
Traceback (most recent call last):
  File "/Applications/LilyPond.app/Contents/Resources/bin/lilypond- 
book", line 59, in ?
    import lilylib as ly
ImportError: No module named lilylib

invoking lilypond by itself I get the ominous reference to:

dyld: Library not loaded: /Users/hanwen/src/maclily/BUILD/build.app// 
Contents/Resources/lib/libintl.1.dylib
  Referenced from: /Applications/LilyPond.app/Contents/Resources/bin/ 
lilypond
  Reason: image not found
Trace/BPT trap


lilypond is a binary file, and I am not user hanwen :-). (I would  
know what to do if I were!)

Any help appreciated...
