Here's what I see:

$ sw_vers
ProductName:	Mac OS X
ProductVersion:	10.8.5
BuildVersion:	12F2560
$ port rdeps highlight
The following ports are dependencies of highlight @3.40_1:
  boost
    zlib
      xz
        libiconv
          gperf
        gettext
          expat
          ncurses
    bzip2
    icu
    python27
      pkgconfig
      db48
      libedit
      libffi
      openssl
      sqlite3
      python_select
      python2_select
  cctools
    libunwind-headers
    llvm-3.7
      libcxx
      perl5
        perl5.24
          gdbm
            readline
      llvm_select
  lua
$ port installed | grep clang
  clang-3.9 @3.9.1_3+analyzer (active)
  clang-4.0 @4.0.1_1+analyzer+libstdcxx (active)
  clang_select @2_0 (active)

I use master from last Sunday and build ports from source with libc++.
