lilypond-profile with zsh

[Némo]

Hello,
something change with lilypond lilypond-profile script for zsh.
I used to remove some lines in the script and then running :
source 
/home/sources/lilypond/lilypond-2.3.x/buildscripts/out/lilypond-profile 
and everything was good.
Now I got this :

Make sure that this script is sourced, ie. run as
   . lilypond-profile
Continuing anyway ...
zsh: exit 2

and running this don't work.


What am I suppose to do ? Maybe the error message should be more clear ?
I'm running Gentoo / zsh 4.2.0
