[Haskell-cafe] confusion about cabal-install install

I'm trying to install cabal-install. I ran: $ cabal update && cabal install cabal-install After compiling, cabal reported: Installing executable(s) in /home/ajs/.cabal/bin Installed cabal-install-1.20.0.1 But now consider: $ cabal --version cabal-install version 1.16.0.2 using version 1.16.0 of the Cabal library $ which cabal /home/ajs/.cabal/bin/cabal $ /home/ajs/.cabal/bin/cabal --version cabal-install version 1.20.0.1 using version 1.20.0.0 of the Cabal library I am confused. My path is set to point to "$HOME/.cabal/bin/:$PATH"
