pyotherside: error: Qt requires a C++11 compiler and yours does not seem to be that

​pyotherside fails to build at least on Mavericks:

clang++ on Mavericks does indeed support C++11 but is not in C++11 mode by default. You have to put it into C++11 mode by using the -std=c++11 flag in CXXFLAGS.

The port also needs compiler.cxx_standard 2011 to tell MacPorts to ensure that a C++11-capable compiler is used.
