Process chutney in a food processor until smooth. Add ketchup and next 4 ingredients, and process until blended. Chill sauce at least 2 hours.
Stir together butter, salt, and pepper; rub over tenderloin. Place on a lightly greased rack in a jellyroll pan. (Fold under narrow end of tenderloin to fit on rack.)
Bake at 500° for 30 to 35 minutes or until a meat thermometer inserted into thickest portion of tenderloin registers 145° (medium-rare). Loosely cover tenderloin with aluminum foil, and let stand 15 minutes before serving. Serve tenderloin with sauce and dinner rolls.
