Cannot set property 'radialIndicator' of undefined

I'm trying to use radialIndicator without jquery in a project where jquery is used for other purpose and I get this error:

Cannot set property 'radialIndicator' of undefined

Inspecting the error I found that the problem is here:

if ($) {
    $.fn.radialIndicator = function (options) {
      return this.each(function () {
        var newPCObj = radialIndicator(this, options);
        $.data(this, 'radialIndicator', newPCObj);
      });
    };
  }

Commenting out this part of code, all is working fine. It would be nice if you add an option to opt-out jquery combining the check of this new option with the if($). Alternatively I don't know if there's a better way to check if the initializations start in jquery style or not.
