That could be a BIG problem. petsc4py does not "officially" support
PETSc builds with static libs, though it could work on some scenarios.
Moreover, even if you get it working, you will not be able to use let
say slepc4py, or any other C code depending on the PETSc libraries
(think of a fast, Cython-implemented Function()/Jacobian() routine for
a nonlinear problem solved with SNES).

I really recommend you to pass '--with-shared' to PETSc's configure.
