Comment(by jonesc@…):

 Root built fine for me with the configure options

 {{{
 ./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
 }}}

 Please try again, in a completely cleanly unpacked root directory, and
 pipe the output from configure and make to file, and attach it to this
 report.

 Chris
