Laravel Spark doesn't pull in css correctly

I am playing around with Spark in order to learn how to use it. I did a new install under Homestead following the install instructions. The css link generated fro the page at the route / is

 <link href="http://ift.tt/1L7VV7k" rel="stylesheet">

No css was generated. So, the home page is jacked.Can anyone help me track down the problem?
