What ghc package does cabal-install need? I've just installed cabal to try and get < but on running cabal-install it throws the error: > cabal: ghc version >=6.4 is required but it could not be found. Apt-cache searching ghc returns literally hundreds of packages, which one do I need?

You need the one called exactly `ghc`.

* Ubuntu: <
* Debian: <



You can add the `--names-only` option to `apt-cache search` to limit your results; it prevents it from returning a positive result for packages that only mention ghc in the description. If that fails, I go to the package search page on the distro website where I can search for filenames instead of package names.
