Re: [Haskell-cafe] errors while installing yesod 0.8

So it appears this is a bug with JSONb-1.0.2. There's a new version out. IS the answer to use that, or to patch this version? On Mon, Apr 25, 2011 at 1:48 PM, Michael Litchard wrote:

The exception was: ExitFailure 1

How do I clear up this ambiguity?

I started mindlessly pasting in the output, and the following lept out at me:

There's more of the same I'm leaving out.

I'm going to see if I can go somewhere with these error messages. If I totally hose things, I'll let you guys know.

So what else can I try?

$ cabal install -v3 monad-control

That should give some hints at which point exactly things fail.
