Hello Haskell-cafers, I used to teach Haskell (and Clean!) at University level but haven't touched Haskell in years and certainly never used it with a Mac. Now I work in publishing and want to experiment with Haskell's web services and see if I can help set up an open-source system for handling ONIX xml data. So I tried to install happstack-server (among several other things) and this depends on unix but cabal can't install unix. Error and diagnostics below as best as I could see to report them. Any tips/pointers much appreciated; I'm not sure if this is a bug or where to report it if it is one... thanks for any help. Matthew. bash-3.2# cabal install unix Resolving dependencies... cabal: cannot configure unix-2.4.1.0. It requires base >=4.2 && <4.4 For the dependency on base >=4.2 && <4.4 there are these packages: base-4.2.0.0, base-4.2.0.1, base-4.2.0.2 and base-4.3.0.0.
