(I already sent a comment on the Shakespeare site but couldn't get too far. So, if this isn't the right place for this issue, I'd appreciate you point me to the right one.) Hi, I can't install yesod. Doing a cabal install yesod-bin or cabal install yesod fails because it fails to build shakespeare. I tried with all versions of shapeare >= 2.0, as required by yesod-bin. Below are all outputs. My environment: OS X 10.6.8, Xcode 3.2 Haskell-platform 2014.2.0.0 ghc-7.8.3 cabal-install 1.22.4.0 using version 1.22.3.0 of the Cabal library. This corresponds to a fresh install of the HP, ghc, and cabal I didn't before trying to install yesod. The developer of Shakespeare suspects that be a bug of HP and suggested I try a clean install of GHC as explained in http://www.stackage.org/install#mac-os-x However, the bindist available there doesn't work with my OS 10.6.8 I have a large screen output from those trials that you can check on the Shakespeare github page corresponding to the thread I started there https://github.com/yesodweb/shakespeare/issues/156 If you prefer, I can paste it here as well.
