I've seen this too. Have you somehow rebuilt directory-1.0.0.0 using Cabal? If so, the Cabal-built library exports different internal symbols from the version built with ghc-6.8.2, even though it's the same source compiled with the same version of GHC. Any library built against the earlier version will no longer work.
