FWIW, PETSc takes less than 3 minutes to build (after configuration) for
me (I build it every day). Building MUMPS (with dependencies) is
automatic with PETSc's --download-{blacs,scalapack,mumps}, but is
involved to do by hand (all three require editing makefiles). I know
people that have configured PETSc just to build code which calls MUMPS
directly (without PETSc). :-)
