Hi Graham, hi Han-Wen,

Similar problem here when I upgraded to 2.11.43-2 on my OS X (10.4 -- *not*
Leopard) box at home this morning. It appears to be a python versioning
problem. The OS directive at the head of lilypond-book is finding python
with #!/usr/bin/python ... which aliases to python 2.3.5 on my system; this
is a spurious python install on my box. I prefer to use python 2.5 and
"which python" gives
/Library/Frameworks/Python.framework/Versions/Current/bin/python, (which is,
in fact, 2.5).

So, what this comes out to mean is that the global references to the set( )
constructor in lilypond-book all break if /usr/bin/python is used because
set( ) didn't become a python built-in until 2.4 (or thereabouts). Yes, I
know it's weird for me to have multiple versions of python installed on my
box and I can't remember why it's like this ... something to do with the
.dmgs I downloaded. But the real solution is for lilypond-book to summon
whatever version of python appears on the user path; in my case this will be
python 2.5, set( ) will be built-in, and everything will work great.

I don't understand lilypond-book well enough to change the version of python
that the script is looking for. But adding ...

  from sets import Set as set

... to the import statements at the head of the script fixes the problem for
now.

Odd that everything worked great through 2.11.41, at least, and the set( )
stuff only becomes a problem in 2.11.43.


### DETAILS ###

Minimal lilypond-book test file:

   \documentclass[10pt]{article}
   \begin{document}
   hello, world!
   \begin{lilypond}
      \new Staff {
         c'4
      }
   \end{lilypond}
   \end{document}

Notice ...

   $ /usr/bin/python -V
   Python 2.3.5

... but ...

   $ which python
   /Library/Frameworks/Python.framework/Versions/Current/bin/python
   $ `which python` --version
   Python 2.5


Then, output from lilypond-book 2.11.43 under OS X 10.4.11:

$ lilypond-book --pdf --out=out test.tex

HTH. Not exactly the same problem Graham was reporting, but perhaps related.
