<div>I've been unable to get sunstone to work. I was running the 1.85 version of ruby and was experiencing the same 'union' issue.  Daniel suggested to another list member try upgrading Ruby to a 1.9 or downgrading the rack release.  Downgrading didn't work,
 so I tried upgrading to 1.9.  I now get a different Ruby error:</div>
