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.

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.

If you installed an experimental GHC version,
it makes sense to install packages into the same directory,
Assuming you downloaded AC-Random-0.1.tar.gz, do the following:
tar xzf AC-Random-0.1.tar.gz
ghc --make Setup
./Setup configure --prefix=/usr/local/packages/ghc-22.214.171.12411219 -p
./Setup build -v
./Setup install -v
Hope this helps!
