If you don't have the CLTools installed, you wouldn't be able to install most 
of MacPorts.  I'm pretty sure you likely have them installed.

Dropping back down to Xcode 7 would mean that Xcode.app would contain the 10.11 
SDK and would workaround your issue, but the issue is that the port isn't 
honoring your SDK (and maybe deployment target) selections (which default to / 
and host os version respectively).
