Well, for graphviz today this seems both as this is what is installed:

modgraph.lua clearly invokes the interpreter, whilst the first two libs
link to the libraries....

are you suggesting more around the USE_TOOLS mechanism of :build :run
like for perl?

that seems like a great idea, leaving buildlink3.mk for linking to 
libraries.
