[Haskell-cafe] Troubles installing EclipseFP

Hi, i'm trying to install eclipsefp. Ubuntu 14.04, ghc 7.6.3, cabal-install 1.20. I did it with a fresh .cabal and .ghc folders. Nothing else was installed. After restarting eclipse it started doenloading and building haskell libs, and stopped with this error: Cabal==1.16.0/installed-c6e..., SourceGraph => Cabal<1.7) rejecting: SourceGraph-0.2, 0.1 (conflict: buildwrapper => Cabal==1.16.0/installed-c6e..., SourceGraph => Cabal<1.5) Backjump limit reached (change with --max-backjumps). Note: when using a sandbox, all packages are required to have consistent dependencies. Try reinstalling/unregistering the offending packages or recreating the sandbox.
