Comment (by RobK88):

 @Ryan -- interesting idea -- using a single port to the current version
 and the legacy version.  But wouldn't that confuse  users?  When one gets
 info on the port (e.g. port info switchaudio-osx), one will see only the
 current version listed.  And when they install the port on an old Mac,
 they may think they are running the most recent version when in fact they
 are not.

 Perhaps having separate ports with the version number in the port name
 makes the most sense.
