Thanks guys. I must have been a little confused by the difference between platform and GHC. I was reading the Yesod book at the time which I think (probably erroneously) mentions GHC 7.2 alongside recommending Haskell Platform, which does not seem possible.

The last release of Haskell Platform has ghc version 7.0.3. There is nothing outdated in arch... You may be referring to the ghc 7.2, right? It is not in Haskell Platform yet.

Yes, that's the reason why our ghc is lagging so much. In fact, we have plans to stop supporting the platform mainly for this reason.

In the near future (hopefully in a month or so), the our extra repository would only contain the latest stable ghc (currently at 7.2.2) and cabal-install (plus its deps).
