Sure thing:

    (control-monad-failure-0.4), (control-monad-failure-0.5.0),
    control-monad-failure-mtl-0.5.0, cpphs-1.8, cpphs-1.9,
    failure-0.0.0.1, happstack-0.3.2, happstack-data-0.3.3

Additionally:

[email protected]:~$ cabal upgrade failure
Resolving dependencies...
No packages to be installed. All the requested packages are already installed.
If you want to reinstall anyway then use the --reinstall flag.

Cheers,
Edward
