Comment (by jasret):

 Could someone please fix this problem?  I ran into this issue several
 weeks ago and tried everything including several Xcode reloads and
 complete MacPorts reinstalls.  I finally stumbled across this ticket and
 found that I needed to build gcc8 on my own system.  Two hours of CPU
 churning later I'm finally whole again.
