A manual install:
http://www.haskell.org/haskellwiki/Cabal/How_to_install_a_Cabal_package of http://hackage.haskell.org/cgi-bin/hackage-scripts/package/uniplate followed by compile of: <--- cut here --- module Main where import Data.Generics.Biplate main = do putStr "hello world\n"

The key difference is the manual installed as: <--- cut here --- /home/evansl/download/haskell/libs/uniplate-1.2.0.1 # runhaskell Setup install Installing library in /usr/local/lib/uniplate-1.2.0.1/ghc-6.8.2 Registering uniplate-1.2.0.1...

So, I've got to figure how to tell cabal install to install in right place :(
