I'm not a haskell user, but I did recently try to install a haskell project on my Debian Squeeze host:

  $ sudo apt-get install ghc6 cabal-install
  $ sudo cabal update
  $ sudo cabal install hakyll

That failed with an error of the form "installing XX version YY requires FOO version BAR". That gave me zero help in completing the installation, and so I gave up.

Don't sudo cabal install whatever. Actually, avoid cabal install without sudo too, unless you're working with software using dynamic recompilation like xmonad. Use cabal-dev instead, this will save you a world of pain.

I'm confused by your comments relating to sudo ..?

That said it seems that cabal-dev is not packaged for Debian. Come the wheezy release of Debian the hakyll project I wished to try out will be available as a .deb, so I'll try it again then.

What I mean is, "cabal install" is usually a bad idea, with or without sudo.

However, you can do "cabal install cabal-dev" and rely on cabal-dev for the rest. It means you don't have a global package cache, but in this case it's really for the best. Don't forget to add .cabal/bin to your $PATH if you want access to cabal-dev.

Thanks; I'll give that a try shortly.

ghc6 ...

We have been at ghc 7 for quite a while now (the Debian package is `ghc`).

You might start to see bit rot.
