[petsc-users] Build error with slepc: Unable to locate PETSc BAMG dynamic library

I guess this won't really work as the order of build should be:
- petsc
- slepc
- bamg
- slepc4py

And its not easy to do this via configure -without hacks. Currently the above build has the order (hence fails):
- petsc
- slepc
- slepc4py
- bamg

I guess the alternative is: build slepc4py separately after petsc/slepc/bamg are built.
