Comment(by Deil.Christoph@…):

 Wow, thanks very much.

 Note that in the ROOT forum thread I mentioned above the ROOT devs said
 the problem might be the "mp" in the llvm binary names and they don't
 support that.
 Maybe you'll have to patch their configure script.

 Again, thanks very much for looking into cling support, I'd really like to
 try it, but don't have time to try and install llvm / clang by hand.
