Comment(by gmainland):

 Unfortunately, a git hash of the ghc repository is not a complete
 repository state---one also needs the hashes of all the library
 repositories too (see utils/fingerprint.py,
 http://hackage.haskell.org/trac/ghc/wiki/Building/GettingTheSources#Trackingthefullrepositorystate).

 The LLVM 3.2 bootstrap bug prevents ghc from even building. Is that not
 the failure you are seeing? It looks like you are just seeing some tests
 fail. The reported bootstrap failure occurred on Linux x64, so you may not
 see it at all.

 For reference, here is the log of the failed perf-llbm build from April
 21:

 http://www.haskell.org/pipermail/ghc-builds/2013-April/000808.html

 It contains a fingerprint, so you can completely reproduce the checkout
 state and see if that version of GHC+libraries bootstraps with LLVM 3.2
 for you on Mac OS X.
