I was trying to use this snippet to experiment with customizing staff line colors:

But I get the following error when trying to compile the snippet in LilyPond:

Parsing...
Interpreting music... 
Preprocessing graphical objects...
Finding the ideal number of pages...
Fitting music on 1 page...
Drawing systems...ERROR: Unbound variable: interval-translate


Any ideas?  I'm using LilyPond 2.13.56  

Thanks,

Odd...I have no clue why interval translate disappeared from the source, but you can easily replicate its behavior.

Add to the top of your document:

#(define (interval-translate iv amount)

  (cons (+ amount (car iv))

        (+ amount (cdr iv))))

And you should be set!
