So-so. Probably the majority of users are still on ghc-6.*, for them, 0.8.2 is the right choice. The page should have two links, one for ghc-6 and one for ghc-7, but I guess the Cabal cabal is too busy doing more important things (like writing code) to always think of updating the web-page.
Luckily the other releases are listed at http://www.haskell.org/cabal/release.
This seems to have solved my issue.
Good. Just a tip, generally, it's easier to get stuff from hackage, http://hackage.haskell.org/package/cabal-install in this case. You can see the dependencies listed there, and see what version fits best with what you have. If something depends on an older version of a library than you have, that's a bad sign. If something depends on a newer version of time, process, directory, random (a couple of others, basically what ghc itself was built with), that's a bad sign too. When in doubt, $ cabal install whatever --dry-run If that says it would install a library you already have, be careful, that may introduce the dreaded diamond dependency problem.
