gcc47 - installation failure, Failed to locate 'lbzip2' in path

[mollymayo4]

I am trying to install port gcc47. I have Xcode 8.3.3 and macOS Sierra 10.12.6. I have tried uninstalling both Xcode and MacPorts and restarting the whole process. I've also reaccepted the Xcode license and cleaned the port between all attempts to install the port. Any suggestions??
