Thanks, I didn't know about the issue with haskell98-1.1 and that's sorted it out. Matthew. On 03/01/2011 09:33, Erik Hesselink wrote:

This happens because haskel98-1.1.0.0 can't be built with GHC 6.12, but lacks the proper version constraints to enforce this. If you add '--constraint=haskell98==1.0.*' to your 'cabal install' command, it will probably work.

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:
