[Haskell-cafe] Could cabal-install shows dependencies as dot or some format?

Hi, I know ghc-pkg could do that. But that is for packages already installed. I'd like cabal-install to do that when it is trying to resolve dependencies. The reason is that, now I got a "Could not resolve dependencies" error. But I could not simply figure out why based on the output of cabal-install. -- 竹密岂妨流水过 山高哪阻野云飞 And for G+, please use magiclouds#gmail.com.
