The version of Cabal shipped with 6.6.1 unfortunately isn't compatible with some 
of those packages, so you have to either (a) get binary versions of the 
libraries, presumably from the same place you got GHC, or (b) upgrade Cabal.

You can also get the sources for arrows from its darcs repository, 
http://darcs.haskell.org/packages/arrows.  The current sources are compatible 
again with the Cabal library in GHC 6.6.1.
