> Is MacPorts mistaken about the system clang's C++11 support?
I don't think so. With a small test program that includes `<future>`, I am
able to reproduce the error if I do not use `-stdlib=libc++`, and when I
do use `-stdlib=libc++` then the problem goes away. This tells us that the
build is not using this flag, even though it should.
It is difficult to tell for sure what the build is doing because the build
system uses silent rules and I do not know how to make it use verbose
rules. I do not know enough about python build systems to know if that is
even possible. Without this, I cannot know for certain which compiler is
actually being used or with which arguments it is being run.
