Been with Haskell just for few days, and thought it would be a good exercise to run a static site generator to get familiar with various tools, and I’m already running into “cabal hell” I think.  :(

$ cabal install hakyll
Resolving dependencies...
cabal: Could not resolve dependencies:
trying: hakyll- (user goal)
next goal: time (dependency of hakyll-
rejecting: time-1.4.2/installed-d67... (conflict: hakyll => time>=1.5 && <1.6)
trying: time-
trying: process- (dependency of hakyll-
next goal: unix (dependency of process-
rejecting: unix- (conflict: time==, unix =>
rejecting: unix-,,,,,,,,,,,,,,,,, 2.0 (conflict: process => unix==
Backjump limit reached (change with --max-backjumps).

I’m running OS X Yosemite 10.2.2 with all the latest versions of  Haskell and cabal.

Thanks  you for listening. :)
