[PyQt] Installing PyQt 5 on Mac OS X (10.6.8 Snow Leopard)

Xcode on OSX 10.6 doesn't have clang++, all c++ is handled directly in "clang", though I think the early versions of clang here don't fully support c++.  You're better off with llvm-g++.  Xcode added clang++ in later versions starting with Lion. 

You should try to use a different qmake spec, either macx-g++ or macx-llvm.
