   Add the following:

   generic
       type Item is private;
--
       with procedure Put(I: in Item) is <>;
--
       package Foo is...

    Now if there is a visible Put procedure which matches the profile,
you are all set.  Otherwise you will have to pass it during the
instantiation explicity:

       with Ada.Integer_Text_IO;
       package Int_Foo is new Foo(Integer,Ada.Integer_Text_IO.Put);
--
