Trying to install yesod 0.8 breaks when it's time to install monad-control. Google wasn't very helpful, nor was the error message I received mlitchard@apotheosis:~/monad-control$ cabal install Resolving dependencies... Configuring monad-control-0.2.0.1... cabal: Error: some packages failed to install: monad-control-0.2.0.1 failed during the configure step. The exception was: ExitFailure 11 note: I've been trying to use the cab command to manage my packages, I get the same error as above when I use cab instead of cabal.I mention this just in case there is some unforseen problem having to do with cab/cabal interaction. Has anyone experienced this problem, or know what I can do to get more useful error messages that might reveal the cause of the breakage?
