Comment:

 A `bin:`-style dependency should only be used if you want to allow a
 binary outside of MacPorts to be able to satisfy the dependency. Usually
 we do not want that. If you only want to allow binaries provided by
 MacPorts ports to satisfy the dependency, but there are multiple ports
 that could provide it, then use a `path:`-style dependency
 (`path:bin/gpg2:gnupg2`).
