[Haskell-beginners] Broken packages after upgrading to Ubuntu 13.04

[Benjamin Jones]

I haven't looked at the non-GHC haskell packages in ubuntu (I install a
bdist GHC, which includes cabal-install, and use that or cabal-dev to
install deps) but note that GHC went from7.4.x to 7.6.x between ubuntu
12.10 and 13.03 and so it wouldn't be surprising if this alone caused build
failures of some modules.
