[Haskell-cafe] Can't install snap (problem with syb)

I uninstalled ghc, removed my ~/.cabal directory, reinstalled ghc, then tried to install snap. I get: $ cabal install snap Resolving dependencies... Downloading syb-0.3.6... <command line>: cannot satisfy -package Cabal-1.14.0: Cabal-1.14.0-0338b6f52e6e6a56054371a110e1d79e is unusable due to missing or recursive dependencies: directory-1.1.0.2-8957520ced1fb19160c3a6126dcccfaa process-1.1.0.1-91185c964ab744c1f3cbca1863d2ba45 (use -v for more information) cabal: Error: some packages failed to install: aeson-0.6.0.0 depends on syb-0.3.6 which failed to install. snap-0.8.0.2 depends on syb-0.3.6 which failed to install. syb-0.3.6 failed during the configure step. The exception was: ExitFailure 1 Any ideas? Mike.
