Sorry, I often try to make sure things go in in the right order. Like, the basic infrastructure changes that went in corresponded to somewhat old pkg_add changes (like two weeks ago).
The check-lib-depends changes went in very quickly, because they were fixing a rather bad bug (old check-lib-depends was NOT checking that WANTLIB were actually reachable through dependencies, which led to packages being impossible to install, but checking okay). As Antoine said, though, pkg_add is pretty much the only part that you need to have the ports tree still running... The next batch of changes should hopefully not affect the ports tree at all, but be self-contained in pkg_add (in fact, I have nothing in the pipe related to ports tree improvements).
