Barry, Here is the new output without debugging.
Thank you.

So do, for example, export PETSC=arch-opt ./configure --with-cc=gcc --with-fc=gfortran --with-cxx=g++ --with-scalar-type=complex --with-clanguage=C++ --with-cxx-dialect=C++11 --download-mpich --download-superlu_dist --download-mumps --download-scalapack --download-parmetis --download-metis --download-elemental make all test then recompile and rerun your example again with -log_summary and send the output. Note that you should not pass --download-fblaslapack nor the fortran kernel stuff.
