You should be able to select MUMPS as solver/preconditioner using some switches for PETSc on the command line. The PETsc manual will tell you how to do that. You can also install MUMPS through deal.II, without (or in addition to) PETSc. See the doc/readme.html for more instructions, but be aware that this isn't trivial.
