CXXFLAGS = -std=c++11 -sdtlib=libc++ in /etc/src.conf (it is said not to affect ports building)
>Description:
Since x11/kdelibs4 is broken on most recent CURRENT with the iconv replacemnet update AND with outdated gcc stuff gone (CLANG only now), a rebuild of important port x11/kdelibs4 via

portmaster -dfr kdelibs ends up with a dropout of port graphics/opencv-core, which also doesn't build separately anymore.
