musicxml2ly problem

[Patrick Schmidt]

Dear list,

I'm encountering the same problem as James Bailey in February 2008: I'm trying 
to convert MusicXML-files to LilyPond-files. Here are the messages I get:

/Applications/LilyPond\ ver.\ 
2.12.2/LilyPond.app/Contents/Resources/bin/musicxml2ly 
/Users/PLS/Desktop/elite.xml
Reading MusicXML from /Users/PLS/Desktop/elite.xml ...
Converting to LilyPond expressions...
Negative skip -1/4 (from position 87/2 to 173/4)
Converting to LilyPond expressions...
Negative skip -1/4 (from position 87/2 to 173/4)

Output to `elite.ly'
Traceback (most recent call last):

    main()
  File "/Applications/LilyPond ver. 
2.12.2/LilyPond.app/Contents/Resources/bin/musicxml2ly", line 2950, in main
    voices = convert (filename, options)
  File "/Applications/LilyPond ver. 
2.12.2/LilyPond.app/Contents/Resources/bin/musicxml2ly", line 2894, in convert
    print_ly_additional_definitions (printer, filename)
  File "/Applications/LilyPond ver. 
2.12.2/LilyPond.app/Contents/Resources/bin/musicxml2ly", line 2793, in 
print_ly_additional_definitions
    for a in set(needed_additional_definitions):
NameError: global name 'set' is not defined

The created ly-file contains nothing but the version command (\version 
"2.12.2"). I'm using Python 2.6.2 on Mac OS X 10.4.11. Is there anybody out 
there …? Thanks for any hint.

Patrick
