prototype bind support?

As temporary work around on top of your file:

Function.bind||(Function.prototype.bind=function(c){var f=this,a=[].slice.call(arguments,1);return function(){a.push.apply(a,arguments);return f.apply(c,a)}});

In case you don't care about handling extra arguments ...

Function.bind||(Function.prototype.bind=function(c,f){f=this;return function(){return f.apply(c,arguments)}});

Until it's solved, of course
