fish @2.6.0: A compiler with support for C++11 language features is required

[snigel]

Fish tries to compile using gcc4.2 and this fails since a newer version is required. I have tried to select gcc49 and add a cc symlink to gcc49 in /opt/local/bin as well, but that doesn't make any difference.

Downloading fish from sources and building it manually without macports using gcc49 works fine.

Probably the cxx11 portgroup should be included in the portfile; this usually takes care of the details of building software that requires C++11 features.
