Comment (by Dygear):

 Out of genuine curiosity, is it possible to build this now? What are the
 terminal commands that the "lay person" like myself would need to run in
 order to get this up and running today? Or is there a time frame for when
 this will "just work" within the `sudo port upgrade` command?
