"make bin-install" is pretty close to what you want, provided you have
"BINPKG_SITES= #empty" in /etc/mk.conf. With a non-empty BINPKG_SITES,
bin-install will:
 a) check whether the package (or an older version) is installed, and
 complain if so (I hacked my bsd.pkg.mk to split this into two
 separate cases, because I think it's not an error for the correct
 version to already be installed, but it is an error for a different
 version to already be installed.
 b) check whether a binary package exists on the local system, and install
 it via pkg_add.
 
 c) loop through all entries in BINPKG_SITES, trying to fetch and install
 a binary package.
 d) if all else fails, do the equivalent of "make package" and "make clean".
