What Khem meant by "don't use PN here" was that DEPENDS_${PN} is not valid. 
You only use such an override when you are dealing with a variable that is 
specific to one of the packages in PACKAGES (${PN} being the main package) - 
typically that is only variables that deal with packaging. DEPENDS (as, for 
example, SRC_URI) is recipe-wide and thus not only do you not need such an 
override, adding one will in fact prevent your additions from having any 
effect.

Cheers,
Paul
