cabal: dependencies conflict: ghc-7.0.3 requires containers ==0.4.0.0 however
containers-0.4.0.0 was excluded because ghc-7.0.3 requires containers

$ cabal install hpath
Resolving dependencies...
cabal: cannot configure HPath-0.0.2. It requires base >=2 && <=4
For the dependency on base >=2 && <=4 there are these packages: base-3.0.3.1
and base-3.0.3.2. However none of them are available.
base-3.0.3.1 was excluded because of the top level dependency base -any
base-3.0.3.2 was excluded because of the top level dependency base -any
