Lately, spack has added git support and now I create a branch of spack where I add my bugfix branch as the default build git repo instead of master to now deal with checksum headaches. 

   With the PETSc build system directly it handles dependencies, that is if you use a PETSC_ARCH and edit one PETSc file it will only recompile that one file and add it to the library instead of insisting on recompiling all of PETSc (as developers of course we rely on this or we'd go insane waiting for builds to complete when we are adding code).

  Satish,

     Is this possible with spack?
