The current release (git-annex-4.20130227, via cabal) fails to install because testpack-2.1.2 fails to install:

    cabal: Error: some packages failed to install:
    git-annex-4.20130227 depends on testpack-2.1.2 which failed to install.
    testpack-2.1.2 failed during the building phase. The exception was:
    ExitFailure 1

Manually installing testpack gives Version testpack-2.1.2.1 which installs correctly. Maybe the dependencies should be updated?
