What steps will reproduce the problem?

Run:

    cabal install git-annex

What is the expected output? What do you see instead?

The current output is the following:

    $ cabal install git-annex

    yesod-auth-1.1.3 depends on certificate-1.3.2 which failed to install.

I'd rather get a message stating how awesome the software I just installed is. :)

What version of git-annex are you using? On what operating system?

  * Debian (testing)
  * GHC 7.4.1
  * Cabal 1.14.0, cabal-install 0.14.0
  * cabal list git-annex says the installing version is: 3.20130107

Please provide any additional information below.

The certificate package version 1.3.2 does not seem to install properly with
this version of GHC (I think).

Version 1.3.3 solves the issue. I don't know if there is a way for me to
override the dependency tree to try to force the version update with
cabal-install, so maybe it's worth filing a bug.

Thanks a lot for git-annex.
