Comment (by raimue):

 I agree with René that the cxx11 port group should add the dependency on
 gcc6/libgcc instead of forcing everyone to install these ports when
 installing clang.

 As far as I see the +libstdcxx variant only adds additional search paths
 to the clang compiler to support `-stdlib=macports-libstdc++`. clang will
 not link or need any files from the gcc ports unless this option is
 specified.
