By the way, I've just moved to fedora after running ubuntu and that uses sudo as default. Thanks for the link to set it up.
You have a list of directories called you PATH that are searched for executable programs. Apparently /sbin used to be in your PATH but isn't under the new OS install. You can check your default PATH with
$ echo $PATH
You can change your default path in your startup scripts (e.g. .cshrc), specific syntax will depend on which shell you are using. I use tcsh, so in ~/.cshrc I have lines like this:
set path = (/sbin $path)
