Maybe some other requirement is missing.

Likely that requirement is a (more) recent version of LilyPond. One of your earlier attachments said \version "2.19.5", and that version required the function definition to begin with
#(define-void-function (parser location name val)(…)…)
The parser and location arguments can be omitted since somewhere in the 2.19 series.

Obviously the actual version!
