[Utkarsh Ayachit]

Michael,

Let me try this on a Moutain Lion myself and I'll let you know. What
projects  are you turning on in your build?

I removed the sysroot flag from the top-level CMakeLists.txt, but then the ParaView CMake setup fails for a reason I can’t seem to understand. I’m attaching the log showing the CMake output. The only obvious thing I see is the Fortran compiler. Is that required?
