[petsc-users] error with wrong tarball in path/to/package

[Satish Balay]

>>>
                    Looking for ML at git.ml, hg.ml or a directory starting with petsc-pkg-ml
                    Could not locate an existing copy of ML:
                      ['ml-6.2']
<<<

So configure was looking for something with 'petsc-pkg-ml' - and it
did not find it. [there was 'ml-6.2' - but configure doesn't know what
it is..]

Yeah the message could be more fine-grained - will chek.
