[petsc-users] PETSc downloading older version of OpenBLAS

[Satish Balay]

Yeah  --download-openblas-commit option is a modifier to --download-openblas - so both options should be specified..

There is a proposal to automatically enable --download-openblas when --download-openblas-commit (or other similar modifier) option is specified - but its not in petsc yet..
