   The 3.1 release defaults now to a single library libpetsc

   The names of the lapack and blas libraries depends on what Blas and LAPACK you are using, so if you hardwired the name then yes you need to change them.

   Note if you used the PETSc makefiles as a starting point for your makefile you would have a completely portable makefile that you would not need to change for different systems and configurations. See for example src/snes/examples/tutorials/makefile and the rule for building ex1
