    Sudoku: Donâ??t use set.update() with multiple arguments
    
    gnome-sudoku 2.30 uses a feature specific to Python 2.6, despite configure.in
    claiming to require only 2.4, and the external dependency set listing 2.5.2 as
    the minimal version.
    
    The attached patch should fix the bug.
