Comment(by paoloyx@…):

 Ok, the work around found at [building exact–image with a different
 compiler]https://trac.macports.org/wiki/ProblemHotlist#compiler page did
 the trick, using ''llvm-gcc-4.2'' as compiler.
 The problem so seems correlated to the ''clang'' compiler, used as the
 default one from XCode 4 onward?
