In a saucepan, dissolve the sugar in the orange juice and vinegar. Add the chile, cinnamon, cumin, and orange peel. Bring to a boil, reduce the heat and simmer for 20 minutes until it becomes a thick syrup. Discard the cinnamon, add the peaches, and simmer for 5 minutes. Stir in the pecans and heat for an additional minute before serving.
