Looks like I did get it from Fink on my 10.5 machine. But, on my 10.6 machine (Snow Leopard Server) it is in /usr/bin; so it is part of the default installation there since I haven't added anything yet to that (brand new) machine. It might be a part of Dev Tools on 10.6; not sure about that. Richard
