That's why I added the "from sets import Set" line.

Here's the problem I get with the version from GUB:

If I apply that patch, it works as expected.  If I change line
1657 to Set instead of set (after adding the "from..." line as
well), then lilypond-book gives a similar error message, about a
different line that involves set().  Even the one-line
  results = set ()
produces such a "global name 'set' is not defined" error.

However, this works just fine:
tsubasa:~ gperciva$ python
Python 2.4.4 (#1, Jan 31 2008, 02:03:55) 
[GCC 4.0.1 (Apple Computer, Inc. build 5363)] on darwin

>>> foo = set()
>>> print foo
set([])
>>> 
tsubasa:~ gperciva$


...
as I said, I don't pretend to understand what's happening.  :(
