http://hackage.haskell.org/cgi-bin/hackage-scripts/package/fingertree-0.0

Always a good idea to check Hackage when dependencies are missing.

The ByteString API documentation, presumably.

As Don said, it's a matter of domain. For small amounts of data, the overhead erases the performance gains - although no one is denying that for medium (like you see on the Shootout) to large amounts of data (up to tera-, I think someone benchmarked) ByteString is excellent.
