exact-image @0.8.4_1 - build failure on osx 10.8

[paoloyx@…]

MacOsX 10.8 (MountainLion), Xcode4.3, Trying to install exact-image 0.8.4_1. As building with clang gives an error, according to ​building using another compiler, i'm trying to build using llvm-gcc-4.2. But i receive the following error:
