title: ghc-pkg check haddock warnings
body: <p>Upon a fresh install of the haskell-platform (via <code>homebrew</code>) (<code>GHC x64 7.6.3</code>) on <code>OSX 10.9.2</code> I receive the following warnings when I run <code>ghc-pkg check</code> (see below)</p>

  </code></pre>
  
  <p>Per the docs: </p>
  
  <pre><code>ghc-pkg check
      Check the consistency of package depenencies and list broken packages.
      Accepts the --simple-output flag.
  </code></pre>
  
  <p>I attempt to run the following command to generate haddock documentation to no avail:</p>
  
  <pre><code>sudo cabal install --reinstall --force-reinstalls --enable-documentation
  </code></pre>
  
  <p>The command was from a similar question a user had on the haskell mailing list.

  <p>How do I appease <code>ghc-pkg check</code> and remove these warnings?</p>
  
  <p><strong>CAVEAT</strong>: When I say "fresh install" I mean I have installed the Haskell-platform from scratch, and installed globally <code>cabal-1.18.0.3</code>and added cabal's bin directory to my path.</p>
