You of course mean cabal-install, not Cabal when talking about recompiling things (I know, I'm being picky, but still...). Also, that problem is the reason why I recognise that for happstack can't at the moment have the QuickCheck dependency optional. -- Ivan Lazar Miljenovic ivan.miljeno...@gmail.com IvanMiljenovic.wordpress.com _______________________________________________ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
