You probably have some packages of yours installed as user and some others globally. Have a look at: http://www.haskell.org/cabal/FAQ.html#dependencies-conflict I recommend that as soon as you have a running Haskell Platform to always install new packages with cabal install ... --user Thomas Am Sonntag, den 23.10.2011, 13:27 +0200 schrieb 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?
