Comment (by jmroot):

 All the actions handled by `action_target` can (by their nature as
 Portfile targets) only run on the current version in the tree. If the
 current version of `foo` is 1.1, it's just as impossible to `checksum foo
 @1.0` as to `install foo @1.0`. The real issue is that we have no way to
 specify "the current versions in the tree corresponding to the ports that
 are installed/active/whatever".

 It's probably good enough to ignore versions added implicitly from the
 registry, and only error if the unavailable version was specified by the
 user. (It would actually be possible to really run targets on the
 specified version if it is installed, by using the Portfile stored in the
 registry. But that would probably be even more confusing.)
