No, you don't need any backend when compiling Cairo. Then you should
just get the image backend and that should work fine.

It should work.
But that doesn't mean that it does work, as pretty much noone ever
compiles Cairo without a backend, so what you are doing probably hasn't
been done in a long time. That said, I don't have an idea where to look.

Good luck finding the problem, and if it's our fault, please send the
solution our way.
