</div><div>This is weird, because on OS X Lion, and with the following versions, it doesn&#39;t fail for me:</div><div><div><br></div></div><blockquote style="margin:0 0 0 40px;border:none;padding:0px">

</div>
<div>Nevertheless, you can try the following to do what cabal asks you to do:</div><div><br></div><blockquote style="margin:0 0 0 40px;border:none;padding:0px"><div>cabal install --ghc-option=-XDatatypeContexts</div>
