Re: [Haskell-cafe] trying to cabal install lambdabot, failure on 'random' package

"show" is the failing package A look on Hackage suggests that "show" had problems with its cabal file at versions 0.4 & 0.4.1 and was fixed at 0.4.1.1. Can you try installing "show" individually at 0.4.1.1 the try installing the rest of lambdabot.
