Thanks very much for your help.  

I renamed the package to APL_Arrays.APL_Data_Arrays and changed the instantiation to

    result : APL_Data_Array_Pointer := new APL_Data_Array'(
               Ada.Finalization.Controlled with 
               g_shape => new Dimensions'(right.g_shape.all),
               g_data  => new Elements(right.g_data.all'Range)
             );

Now it compiles properly.
