Honestly, I think that is debatable. It would also make the port file a 
mess.

You would have to find a way to prevent root from automatically finding 
the libraries under /opt/local. I suspect if you just remove all the 
dependencies, it will still find then.

Honestly, I think you are flogging  a dead horse a bit here. Unless you 
can find a clean way to get it working within MacPorts, my vote is just 
to flag root6 as only working on 10.9 (or 10.8, depending on if it works 
there or not) and beyond.
