Comment (by macports@…):

 MacPorts uses the system compiler to compile itself, not gcc49. The
 underlying error is this:
 {{{
 configure:3229: /usr/bin/cc --version >&5

 You have not agreed to the Xcode license agreements, please run
 'xcodebuild -license' (for user-level acceptance or 'sudo xcodebuild
 -license' (for system-wide acceptance) from within a Terminal window to
 review and agree to the Xcode license agreements.
 }}}

 In this case, you most likely need to accept it as root using ```sudo
 xcodebuild -license```
