And yet that's exactly the problem we seen with early maemo5 upgrades, like PR1.0 ->PR1.0.1 iirc
Binary file replacement - as suggested - is one way, but You could also grab vanilla camera-ui package, unpack it, edit control files to mimic CSSU'ish camera-ui, and pack it again - installing such version should satisfy dependencies. While it's more elegant solution than just replacing binaries, it's still dirty hack, and You will need to redo it with every update of CSSU's camera-ui (to mimic next version).
