I just got everything to work. I needed to set the OSX variables in CMake. When I did this for the git version, it all compiled correctly. Below are the three needed settings. Where is the best place where we can document this for others?<br>
<br>
Thanks,<br>

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.<br>
