hi,
I am trying to build git annex on lenny.
I checked out the latest from git c88d4939453845efee04da811d64aa41046f9c11,
installed all the packages (some from backports) as required by dpkg-buildpackage
Then I get this:
...
mkdir -p build
ghc -odir build -hidir build --make git-annex

make: *** [build] Error 2

I will try to check the mentioned file for error, but I do not know how to program in haskell.
Thanks for your help! --[[cstamas]]
