Assuming you're set for VHDL 1993 compilation (the default) you dont need a component declaration at all. Use this method instead: 


pll1_inst : entity work.pll1 PORT MAP (
  areset     => areset_sig,
  inclk0     => inclk0_sig,
  c0     => c0_sig,
  locked     => locked_sig
);

This method looks for the entity in the source file instead (make sure the pll1 source file is included in the project).
