In a mixing bowl, blend pumpkin, cinnamon, cloves, salt, sugar, eggs and milk. Pour mixture into a 9x13 inch baking dish. Sprinkle dry cake mix and nuts over the batter. Pour melted butter over the cake.
Bake in a preheated 350 degrees F (175 degrees C) oven for 60 minutes and let cool. The cake will be "liquidy" at first, but will solidify as it cools.
