[PD] linking libs with pd-lib-builder (was Re: fluid~)

[Christof Ressi]

Me and Dan have been pointing you to "-install_name @loader_path". Just 
do what pd-lib-builder does with shared helper libraries. Unfortunately 
I don't have time to come up and test a complete solution, but if you 
don't know how makefiles work already, that might be a good reason to 
start ;-)
