Comment(by jonesc@…):

 Also, why did you select an old llvm version to activate, instead of the
 latest ?

 I have

 {{{
 llvm-3.1 @3.1-r154872_0+assertions
 clang-3.1 @3.1-r154872_0+analyzer+assertions
 }}}

 Please completely uninstall all your llvm and clang versions, make sure
 you have the latest port versions installed, and try again.

 Chris
