If a com wrapper around a .net DLL uses one more dependent .net DLLs, should they be placed in GAC?

If a managed DLL uses one or more managed DLLs, and a com wrapper is built around the managed DLL, then should all the dependent managed DLLs be placed in GAC. I am getting an "unable to find assembly..." in a similar scenario. Thanks in advance.
