</pre>
it fails on OSX 10.6.x with ghc 6.12.3 and a corresponding haskell-platform install. I ran a bisect and found that commit 75a3f5027f74565d909fb940893636d081d9872a seems to have broken git-annex for me, reverting the commit allows me to build git-annex, I have not run the tests to verify everything is working correctly though.
