The port makefile can't just add stuff to the software's Makefiles.
If the software has a "good" makefile, then either of these (in the port
Makefile, in order of preference) should work:
LDFLAGS+=	-L/usr/local/lib
-or-
LIBS+=		-L/usr/local/lib
-or-
CFLAGS+=	-L/usr/local/lib
CXXFLAGS+=	-L/usr/local/lib

If that doesn't work, then yes, you have to edit the software's Makefile.
