+ make -C petsc-3.7.3 PETSC_DIR=/builddir/build/BUILD/petsc-3.7.3/petsc-3.7.3 PETSC_ARCH=x86_64 streams

I don't think this is necessary - its primarily for users to verify their machine performace - before
analyzing PETSc application performance

+ pushd petsc-3.7.3/src/ksp/ksp/examples/tutorials
~/build/BUILD/petsc-3.7.3/petsc-3.7.3/src/ksp/ksp/examples/tutorials ~/build/BUILD/petsc-3.7.3
+ make ex50

Or this stuff.. [since 'make test' already does basic non-liner test]

Hm --with-64-bit-indices=0 --with-64-bit-indices=1 --with-blas-lib=-lopenblas64 --with-lapack-lib=-lopenblas64 --known-64-bit-blas-indices=1

Hm - this --known-64-bit-blas-indices=1 was primarily tested with MKL - assuming its not isssue with -lopenblas64 [thats triggering the SEGV]

Will check..
