Today, it is very unusual to use GHC by itself. To use Haskell, you install the Haskell Platform. That is GHC together with Cabal and a basic set of libraries. It is very easy to install.
However, since you are willing and able to test bleeding-edge versions of GHC, you need to be able to live without the platform, which typically catches up to GHC versions only within a couple of months.
Almost all Haskell software is expected to be installed using Cabal nowadays.
It is important to know that people associate two packages with the name ``Cabal'': * cabal : package infrastructure shipped with GHC --- only a library. * cabal-install : package manager requiring a number of other packages (in particular networking packages), and providing the executable ``cabal'' Life without cabal-install is not only possible, but also safer. (See also: http://www.vex.net/~trebla/haskell/sicp.xhtml ) If you installed an experimental GHC version, it makes sense to install packages into the same directory, say /usr/local/packages/ghc-7.4.0.20111219. Assuming you downloaded AC-Random-0.1.tar.gz, do the following: tar xzf AC-Random-0.1.tar.gz cd AC-Random-0.1.tar.gz ghc --make Setup ./Setup configure --prefix=/usr/local/packages/ghc-7.4.0.20111219 -p ./Setup build -v ./Setup haddock ./Setup install -v Hope this helps!
