With the advent of the cxx11 1.1 portgroup and the associated changes that allow clang to build using newer gcc's libstdc++, it is no longer mandatory to use LibcxxOnOlderSystems to be able to build software that uses C++11.

But the port in question does need to provide the right flags to the compiler; the lz4 port doesn't. Therefore users doing LibcxxOnOlderSystems would encounter a build failure for this port too, until this problem is fixed. I'm looking into fixing this problem. It is not something a user should need to "hack around"; if adjusting the portfile to work with cxx11 1.1 or LibcxxOnOlderSystems was necessary, then it merits filing a bug report (so that we can fix it so that other users don't need to hack it) as you did for lz4:
