HaXml-1.13.2 needs pretty and containers as additional "build-depends" in HaXml.cabal for ghc-6.8.x (HaXml-1.13.3 should work). I don't know about http://hackage.haskell.org/cgi-bin/hackage-scripts/package/HaXml-1.19.1 > So I installed "pretty-1.0.0.0" package as well. bad move, Cabal itself depends on (this) pretty (package). Reinstalling pretty failed and spoiled you're installation. Maybe such kind of (re-)installation should be prohibited somehow.
