Okay, this happens a few levels down. Here is the error:

TEST setInstallDir from
PETSc.options.installDir(/global/u2/m/madams/petsc_install/petsc/config/PETSc/options/installDir.py:39)
TESTING: setInstallDir from
PETSc.options.installDir(config/PETSc/options/installDir.py:39)
   setup installDir to either prefix or if that is not set to
PETSC_DIR/PETSC_ARCH
          Error trying to to test write permissions on directory [Errno 30]
Read-only file system:
'/global/common/software/m1041/petsc_install/petsc_knl_intel/PETScTestDirectory'
            Defined make macro "PREFIXDIR" to
"/global/common/software/m1041/petsc_install/petsc_knl_intel"

It makes you use sudo because it cannot write to the prefix directory.

  Thanks,

     Matt
