Comment(by jonesc@…):

 OK, seeing as I had already configured root, it seemed rude not to try and
 build it ...

 Bottom line is I can build root fine with MacPorts clang version, using

 {{{
  > ./configure --with-llvm-config=/opt/local/bin/llvm-config-mp-3.1
 --with-clang --with-cc=/opt/local/bin/clang-mp-3.1 --with-
 cxx=/opt/local/bin/clang++-mp-3.1 --with-ld=/opt/local/bin/clang++-mp-3.1
 --enable-builtin-glew
 }}}

 However, if I try and enable cling I get

 {{{

 }}

 I'm not sure, but it looks like this file is part of clang's API

 http://clang.llvm.org/doxygen/ASTContext_8h-source.html

 But, its missing on my system.

 Does anyone know if Macports clang ports install the API headers etc. ??
