[Haskell-iPhone] Clarifications on building from source on Lion

I'm stuck with OS 10.7, and I'm not sure if it's possible to build ghc-iphone or not with the new llvm compilers. To clarify the build process: does the source of this project consist of the 25 patches in the snow leopard directory? Do I force all these patches to apply to GHC 6.10.4, or do I only apply the patches that are specified for this version (i.e. patch 22 is for 6.10.4, but most seem to be for 6.10.2). Supposing I get this to build, is there any hope that compiling against the new iOS 5.0 sdk (using the llvm c compilers) will work, or should I just wait for this new ghc 7 cross compiling port to be finished?
