You've instantiated LUT6_2 but you have no required component declaration for it, like this:

architecture rtl of luts_vhd is
     component LUT6_2
           generic (INIT: std_logic_vector(15 downto 0);
           port(
                A,B,C,D: in std_logic;
                O: out std_logic);
      end component;
