jQuery 1.5.1 & Chrome/Safari - jQuery errors

jQuery 1.5.1 & Chrome/Safari - jQuery errors

jQuery won't appear to load properly on Chrome and Safari for a website I'm working on. (I'm using the jCycle plugin on the page). It works everywhere else including IE6. I can't tell from the errors if the issue is with jQuery itself or the plugin.

Here's the error I'm getting:
  1. Uncaught TypeError: undefined is not a function
    1. jQuery.jQuery.extend._Deferred.deferred.resolveWith jquery-1.5.1.js:869
    2. jQuery.jQuery.extend.ready jquery-1.5.1.js:420
    3. jQuery.DOMContentLoaded jquery-1.5.1.js:1055

I'm unfamiliar with how Chrome/Safari reports errors. But it seems to me this call stack would show my originating jQuery call if the error originated from my code. But I don't see any of my code in this call stack.

Anyone got any pointers on where I can start looking to get this fixed? You can see the page with issues at:
