All of this is very frustrating for someone eager to lean Haskell and running into this. I have now looked at stack and stackage and better understand the differences and similarities and will probably try to favor stack over cabal. As well I have looked further into cblrepo and the ability to create an Arch package to install via pacman, but I guess that\s further down the line. As an alternative to ghc-vis, I looked at vacuum but running into similar problems. I was basically looking at a way both to visualize data and so stepwise evaluation in Haskell, to help me better understand the language, functions and expressions, etc. I guess I will focus on the debugger for that and see if I can find my way around. Any other suggestions, please feel free. _______________________________________________ arch-haskell mailing list arch-haskell@haskell.org http://mail.haskell.org/cgi-bin/mailman/listinfo/arch-haskell
