You have to have _some_ sparse symmetric linear solver. HSL is probably the
easiest, because it uses fortran 77 constructs; all the others require fortran
95, and MUMPS, the one with the least restrictive license, requires a fortran
compiler that can understand embedded preprocessor information. 
(Alternatively,
you can send MUMPS code through a C-preprocessor first.)

The steps for working with the solvers is described quite well, I 
think, in the
user's manual.
