Gracefully fail in IE < 6

[ajpotts]

Is there any simple way not to fire errors in IE < 6?

Having put up a window.onerror => server logging feature, I'm still getting a significant number of users firing off jquery errors because they're using 5.5 or 5.0. I'm not expecting it to work, but not expecting it to cause pop-up errors either.

Alternatively, is there any possible workaround, e.g. [pseudo-code]

<!--[if IE &lt; 6]>
jquery = null;
<![endif]-->
