Comment(by jonesc@…):

 I suspect your problem is you have a rogue installation of LLVM somewhere
 that is being picked up, outside of the MacPorts one, and conflicting.

 Where is the library 'libLLVM-3.1svn.dylib' that the build log refers to.

 Clean out all other llvm and clang installations other than the 'official'
 MacPorts ones, and try again.

 Chris
