Error while compiling "third_party" in Mavericks 10.9

Start with the sparsehash compilation failure and the reported Xcode toolchain, then inspect src/hashtable_test.cc and the third_party build entry point. Done means establishing whether the project can compile successfully on the stated Mavericks environment, but the repository description says development moved to ps-lite.
