Hi all, This might be a very stupid question to u all, but i really not sure. Is it necessary to uncompile my old bind, before i compile the lastest one? Or i should install it on top of it? In general, is there a way to uninstall/uncompile softwares in unix world if it is not a package, like Windows. Like bind, is there a way to uninstall to old one? thanks all, Derrick
