Cabal: Could not resolve dependencies (yesod)

Hi,

I try to install git-annex master with cabal, so I cloned the git repo and run "cabal install --only-dependencies". This gives me the following error:

Resolving dependencies...
cabal: Could not resolve dependencies:
trying: git-annex-3.20120826 (user goal)
trying: git-annex-3.20120826:+oldyesod
trying: git-annex-3.20120826:+currentyesod
next goal: yesod-default (dependency of git-annex-3.20120826:+oldyesod)
rejecting: yesod-default-1.1.0 (conflict: git-annex-3.20120826:oldyesod =>
yesod-default(<=1.0.1.1))
rejecting: yesod-default-1.0.1.1, 1.0.1, 1.0.0, 0.6.1, 0.5.0, 0.4.1, 0.4.0,
0.3.1 (conflict: git-annex-3.20120826:currentyesod => yesod-default(>=1.1.0))

Any idea how to fix this? (PS: I'm running Kubuntu 12.04)

Cheers, Tobias

Hmm, cabal is not as smart as I'd hoped it could be. I've removed the support for old version of yesod.

thanks, that resolved the dependency trouble. But now:

Building git-annex-3.20120826...
Preprocessing executable 'git-annex' for git-annex-3.20120826...

Utility/Yesod.hs:15:8:
    Could not find module `Data.Default'
    It is a member of the hidden package `data-default-0.5.0'.
    Perhaps you need to add `data-default' to the build-depends in your .cabal file.
    Use -v to see a list of the files searched for.
