[Haskell] cabal conflicting rules

[Claudio Nieder]

Hi,

I just get this output from cabal:

 cabal install leksah
Resolving dependencies...
cabal: dependencies conflict: ghc-7.0.4 requires array ==0.3.0.3 however
array-0.3.0.3 was excluded because ghc-7.0.4 requires array ==0.3.0.2


How can it be that the same package (ghc-7.0.4) asks for two different 
versions (array 0.3.0.3 / 0.3.0.2) excluding each other?
