Links to Cabal documentation from the user guide are broken

At http://www.haskell.org/ghc/docs/7.8.2/html/users_guide/packages.html there are two broken links to Cabal documentation, there's also a broken absolute link to the same place from the haddock documentation.

$ find ./share/doc/ghc -name "*.html" -exec grep -H "Cabal/index.html" {} \;
./share/doc/ghc/html/haddock/invoking.html:    tool <a class="ulink" href="http://www.haskell.org/ghc/docs/latest/html/Cabal/index.html" target="_top">Cabal</a>
./share/doc/ghc/html/users_guide/packages.html:    <a class="ulink" href="../Cabal/index.html" target="_top">Cabal documentation</a>
./share/doc/ghc/html/users_guide/packages.html:      <a class="ulink" href="../Cabal/index.html" target="_top">Cabal</a> infrastructure

I suppose the right place for all of these links is probably http://www.haskell.org/cabal/users-guide/ ?
