Sprinkle the dried yeast over 1/4 cup warm water in a small bowl.
In a large bowl, mix flour with wine, olive oil, remaining 1 cup of water, and salt, and pepper, to taste. Stir in the yeast water and work it into the dough with your hands. Transfer to a lightly floured board and knead until it just loses its stickiness. Set aside, covered with a damp cloth.
Warm 1/4 cup olive oil in a saute pan over medium-low heat. Add the leeks and cook gently 15 minutes, or until soft but not browned. Add the milk and cook 5 additional minutes. Stir in sugar and cook another 5 minutes. The leeks should be very soft. Add the anchovies, black olives, parsley, and tomatoes. Stir to mix well and continue cooking until the sauce is thick and liquid has evaporated. Remove from heat. Drain the raisins and stir into the tomato mixture.
Lightly oil a 12-inch pizza pan. Divide the dough into 2 pieces, 1 slightly larger than the other. On a lightly floured surface, roll the larger piece out to 1/8-inch thickness and place on the pizza pan. Spread the filling evenly across the dough, leaving a 1-inch border around the edges. Roll out the other piece of dough and fit it on top of the first, and roll the edges of the 2 pieces of dough together. Brush the top crust with oil, sprinkle with sugar, prick in several places with a fork, and set aside for 30 minutes.
Preheat the oven to 450 degrees F.
Bake the calzone in the oven for 15 minutes, then turn the heat down to 350 degrees F and bake another 30 minutes. Serve hot or at room temperature.
