Don't worry, the logic in Uses/compiler.mk is confusing to me too :-)
The c++NN vs gnu++NN difference is usually not noticeable as far as I
know so either one works regardless of whether the port is being built
with GCC or Clang.
As for the compiler.mk arguments, my understanding of c++11-lang means
"this port needs a compiler that supports C++11, but not necessarily a
standard library compatible with C++11". The ports infrastructure then
finds a suitable compiler by checking ${CXX} and falling back to some
devel/llvm* port or lang/gcc* depending on architecture and
$FAVORITE_COMPILER. USES=3Dcompiler:c++11-lang does not provide anything
GCC-specific.
