i enabled lua and imlib2 recently, if you want to test just install those two dependencies manually. i don't think i can enable cairo, although cairo can support opengl or qt as an output device, conky is built with that stuff missing. i'd have to take the cairo source and find what we need there, do something with tolua++, and then patch conky again to use the new functions. i really don't understand anything i just said, so don't expect me to do that right now
