Still very new here. I'm trying to install HaXml and I've updated cabal. I see that a similar issue was posted recently as a bug http://hackage.haskell.org/trac/ghc/ticket/4513 but one that's supposedly fixed; do I need to wait for something or can this be fixed some other way? I think I've posted all necessary version numbers below: ~ $ sudo cabal install HaXml-1.20.2 --global Resolving dependencies... Downloading haskell98-1.1.0.0... Configuring haskell98-1.1.0.0...
