Install clang development headers

[cjones051073 (Chris Jones)]

Hi,

I'm looking into an issue with a variant to the ROOT port, cling, that builds a command line interpreter based on clang. The build is failing, due to missing clang headers. See

​https://trac.macports.org/ticket/34171

for the details. The main error is

/Users/chris/Projects/root/core/meta/src/TCintWithCling.cxx:26:10: fatal error: 'clang/AST/ASTContext.h' file not found
#include "clang/AST/ASTContext.h"
         ^

I've tried build clang myself from source, using the instructions at

​http://clang.llvm.org/get_started.html

and doing so I do indeed get the missing headers.

Is there any reason why this are excluded with the MacPorts build ? If not, could I request that these are added in a future version ?

cheers Chris
