Comment (by dimpase):

 there is a little thing we never got around to fix in `generic_backend`:
 {{{
 +        ValueError: 'solver' should be set to 'GLPK', 'Coin', 'CPLEX',
 'Gurobi', 'CVXOPT' or None.
          sage: default_mip_solver(former_solver)
      """
      global default_solver
 @@ -917,7 +921,7 @@ def default_mip_solver(solver = None):
              return default_solver

          else:
 -            for s in ["Cplex", "Gurobi", "Coin", "Glpk"]:
 +            for s in ["Cplex", "Gurobi", "Coin", "Glpk", "Cvxopt"]:
 }}}
 here the lists of solvers (in both `+` lines) should mention PPL, too.
 Please fix this.
