[petsc-dev] trouble building petsc4py-dev

[Barry Smith]

   Before actually running the cythonize petsc4py should check that the cython version is "good enough" and print a helpful error message otherwise. It should not rely on the "send complaining email; get response email telling to upgrade package X" model of version control. Recommend you add this check.
