 > Doesn't `libc++` have exactly the same problem?

 To some degree yes, although its not as bad as using libstdc++ from gcc.

 For instance on <OSX10.9 the variants pythia and xrootd do not work, they
 fail to build, as those ports use the default c++ runtime, which on the
 older systems is the system libstdc++. You must understand forcing the use
 of libc++ was only ever a last resort solution, and only works because we
 are lucky enough that the core default port doesn't happen use any
 libraries that use another c++ runtime, otherwise it would not work... If
 a user really wants to be safe, and/or gets these variants to work, they
 need to rebuild their entire MacPorts stack using libc++ as the default
 runtime, with all the untested issues that would likely throw up ...
