Comment (by jmroot):

 The cxx11 portgroup doesn't really handle this case very well. Also 2.6.0
 sort of works backwards compared with 2.5.4 in terms of choosing a
 compiler and stdlib: it first decides on a value for configure.cxx_stdlib
 based on cxx_stdlib and the required language standard, and then chooses
 compilers that can use the chosen stdlib. There could be room for
 improvement when a port starts with a compiler choice and wants the rest
 to match that.

 Anyway, yeah, if you want to use a stdlib that is incompatible with what
 the other ports are using, you have to explicitly set it in the portfile.
