I rolled my own from scratch, as much as an exercise in Haskelling than anything else (because I'm far from pro). I will try to make it available soon, but the current amount of documentation required for somebody who isn't me to use it outweighs the amount of work required for me to get it into a more understandable/usable state. ;) pete
Cool :) There's no reason not to simply reuse the arch-haskell name and resources (e.g. this list, the irc channel, the arch wiki pages) to revive/restart. (Maybe too many people associate arch-haskell with useless now, but I think we can turn that around...)
I encourage you to release your stuff early, to get contributions from others (like me) even before it's "ready".
Currently I am using [haskell] and [haskell-extra] and it is fine for my needs. The first is from arch-haskell (xsounds.org/~haskell) and the second is from Fabio Riga (archhaskell.mynerdside.com). Both are built using cblrepo.
What are you using? Is it superior?
