Oh, I figured it out. You can make `nix-env' spit out the
attribute names for packages:
nix-env -qa --attr-path '*' | egrep cabal
So I was able to install it like this:
nix-env --install -A
nixpkgs_unstable.haskellPackages_ghc6122.cabalInstall080
The "package within a package" is a concept unfamiliar to
me.
