[Haskell-cafe] [ghc 6.6] Where is FGL now?

In ghc 6.4, I used Data.Graph.Inductive (aka FGL): % ghc-pkg list /usr/lib/ghc-6.4/package.conf: ... fgl-5.2, ... In ghc 6.6, it seems it disappeared. ghc-pkg list does not show it, the compiler says "Could not find module `Data.Graph.Inductive'" but it is still documented in http://www.haskell.org/ghc/docs/latest/html/libraries/index.html and the ghc 6.6 changelog does not mention its removal.
