</div></blockquote><div><br></div></div></div><div>GLFW is the package that failed to install.  The reason for that should be in the scroll back somewhere but it can often be hard to find when it&#39;s buried in a huge list of compilation messages.  If you try with just GLFW, eg., cabal install GLFW, then it should be easier to spot the error.</div>


<div><br></div><div>Since you&#39;re on a mac, I would highly recommend getting the latest haskell platform.  You&#39;re on 7.0.2 which has bug fixes that are relevant to build failures on OSX, as I understand it.</div><div>
