errors when updating syntax on Mac

[James B. Wilkinson]

I had a file claiming to be version 2.18 and opened it in Lilypond 2.22 on a 
MacBook Pro running Mavericks. When I chose "Update syntax” from the Compile 
menu, lilylib.py threw errors indicating that Python 2 was running and not 
Python 3. I added a line to that file asking it to print the version and got 
2.6.6 from Apple. On a suggestion from the users’ list I found convert-ly.py 
buried in the Lilypond.app directory structure and ran it from the terminal on 
my file. It worked like a champ. The resulting updated file compiled with no 
errors.

The user’s list said that I should report the problem on this mail group.
