Infoboxes are just templates. Wikia seems intent on pushing its NewSpeak, wherein "infobox" means Wikia's proprietary xml "portable infoboxes." But infoboxes are just templates in the rest of the world.

DPL = DynamicPageList

You'd have to request Wikia to install the DPL extension on your wiki. It appears not to be installed there currently.
