Comment (by kencu):

 I was thinking of adding it here:
 {{{
  elseif {${subport} eq "clang-${llvm_version}"} {
     homepage            http://clang.llvm.org/
     description         C, C++, Objective C and Objective C++ compiler
     long_description    Clang is an "LLVM native" C/C++/Objective-C
 compiler, \
                         which aims to deliver amazingly fast compiles
 (e.g. \
                         about 3x faster than GCC when compiling
 Objective-C \
                         code in a debug configuration), extremely useful
 error \
                         and warning messages and to provide a platform for
 \
                         building great source level tools. The included
 Clang \
                         Static Analyzer is a tool that automatically finds
 bugs in \
                         your code, and is a great example of the sort of
 tool \
                         that can be built using the Clang frontend as a \
                         library to parse C/C++ code.

     depends_lib         port:libxml2 port:libomp port:llvm-${llvm_version}
 port:python27
     depends_run         port:clang_select port:ld64
     depends_skip_archcheck-append ld64
 }}}
 adding it to the depends_run section, and probably also to the
 depends_skip_archcheck section
