[Haskell-iPhone] GHC 7.4.1 support?

Hello, I'd like to get started using Haskell on the iPhone.  While I see the support for version 6, there seem to have been a number of patches accepted for ARM and cross compiling support.  Is it possible to use GHC 7.4.1?  Or should I use the older version and wait for a later update? Thanks for any help, -Greg
