Before doing a fresh configure to a CLEAN build directory, set the CXX_FLAGS environmental variable to "-stdlib=libc++", with "export CXX_FLAGS=-stdlib=libc++". CMake should pick that up and place it in the CMAKE_CXX_FLAGS variable, also I think SCIFIO does some type of external project, so hopefully this environmental variable will help it get propagated there too.

I also built 4.5.0 from scratch yesterday, and it worked fine until I enabled "Module_SCIFIO" at which point it gave the same error as the git version.  At least it's consistent!
