Comment(by dports@…):

 I'm not convinced this is a good idea. If anything, we'd have to do the
 check in *both* the pre-activate and post-deactivate phases. If we did it
 only in post-deactivate, the check would never get run on the first update
 after this change (because the old version didn't have the post-deactivate
 hook and the new version didn't have the pre-activate hook). Or it might
 not be possible to unload the kext (because there are running file
 systems) in post-deactivate, but succeed when activating the new port.

 Really, I'm not sure we want to unload the kext when uninstalling the
 port. We don't, in general, shut down running software when uninstalling a
 port. Any reason it's especially important to do so here?
