Take a look here to what I'm currently using:

http://code.google.com/p/petsc4py/source/browse/conf/core/confcore.py#144

I'm not saying that this is optimal, I've always used what PETSc provides.

Perhaps that could work, but...

That's what I was used to get with PETSC_LIB_BASIC. That variable
expanded to "-lpetsc" for single-lib builds, and "-lpetscts
-lpetscsnes ..." for the multi-lib case.

If you could provide the correct list of PETSc libs in
PETSC_LIB_BASIC, that would be nice, because my code would continue
working with previous 3.0.0 and 3.1 releases.
