Maybe it will good, when you give a link to the extensions you mean :) I think the first you mean this one? This Extension is really old and not supported anymore, so i think it's impossible to use it with newer MW versions without muc of own work :)

P.S.: MediaWiki 1.21 isn't supported, too. Please upgrade to the newest relase, MediaWiki 1.23, or at least to release 1.22. More information you can find here, Upgrade information here.
