How are you planning to use petsc4py? Are you going to embed Python in
a C/C++ app?  Is he core PETSc library going to be linked to other
extension modules? I ask this because petsc4py do works with static
libraries,  moreover I managed to support static builds of PETSc and
SLEPc/TAO and still get petsc4py and slepc4py/tao4py working fine (it
only works on Linux, and likely on others POSIX systems excluding OS
X). I do not promote this feature because novices usually make a mess
when link Python modules with static libraries.
