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

[Magicloud Magiclouds]

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.
