[Haskell-cafe] haskell platform question

[Tim Docker]

I'd like to build the haskell platform against a recent GHC snapshot, 
for testing purposes.

I see that I can download the source for the platform from:

      
http://lambda.galois.com/hp-tmp/2011.2.0.1/haskell-platform-2011.2.0.1.tar.gz

with instructions:

     http://www.vex.net/~trebla/haskell/haskell-platform.xhtml

However when I tried this some months ago, I found that some of the 
packages in the above source fail to build due to recent ghc changes (eg 
it's stricter handling of bang patterns).

Is there a more recent "beta" snapshot of the platform? Or a darcs/git 
repo somewhere? I imagine wanting to build the platform against bleeding 
edge ghc would be a pretty common desire.
