question about VHDL library

Hi all, when I compile my VHDL design, there is always a error saying that * design library "book_lib" does not contain primary unit "utils_pkg"*. Does anyone know how to fix it?Thanks ...

library uses are usually ended with a semi-colon (;).

Not necessary: you can write a comma separated list of things to use. 

use ieee.NUMERIC_BIT.all, ieee.std_logic_1164.all;

is the same as: 

use ieee.NUMERIC_BIT.all;
use ieee.std_logic_1164.all;
