Can't build with Ogre 14

[furrykef]

When trying to build with Ogre 14, I get the following error:

cegui/src/RendererModules/Ogre/Renderer.cpp:651:53: error: ‘class Ogre::Camera’ has no member named ‘getProjectionMatrixRS’; did you mean ‘getProjectionMatrix’?

getProjectionMatrixRS was listed as deprecated in Ogre 13. Unfortunately, it has no suggestions for how to replace it; it says merely "do not use".

This issue is a showstopper for me because I'm trying to make an Arch package that depends on the cegui package (which uses 0.8.7), which in turn depends on the ogre package, and that package uses Ogre 14. So I can't get the cegui package to build and I don't know what patch to make to it because I'm not familiar at all with Ogre or with this type of programming.
