MPIGuard fails (gcc 6.2 + mpt 2.12r6)

The MPIGuard fails right off the bat when I run 'dunecontrol make build_tests' (see the attached log file + dune-common/build-cmake/CMakeCache.txt). I am using gcc 6.2 + MPT (the SGI MPI) 2.12r6. All modules are from the master.build_tests.logCMakeCache.txt.zip
