Aldec Active-HDL - No Default Binding Errors

I'm getting some errors when I try to compile my design in Aldec's Active-H DL.

# Warning: ELAB1_0026: BITADJ128.bde(BITADJ128.vhd) : (79, 0): There is no default binding for component "buf". (No entity named "buf" was found). # Warning: ELAB1_0026: BITADJ128.bde(BITADJ128.vhd) : (157, 0): There is no default binding for component "INV". (No entity named "INV" was found). # Warning: ELAB1_0026: BITADJ128.bde(BITADJ128.vhd) : (277, 0): There is no default binding for component "GND". (No entity named "GND" was found).

I have added these items to the library multiple times, and in different wa ys, but it still gets hosed up. I'm wondering if anyone else has had a simi lar issue? I inherited a large design I'm converting from EDIF to VHDL and switching from Virtex-4 to Virtex-5, and there seems to be a symbol resolut ion problem.

Thanks all!
