title: Issues running tests with cabal and HUnit in haskell ('builds-depends' failed.)
body: <p>I trying to run my first haskell program using cabal and HUnit.  I seem to have trouble with my .cabal as I get the error:</p>
  
  <pre><code>λ cabal test
  .\haskell.cabal has been changed. Re-configuring with most recently used
  options. If this fails, please run configure manually.
