There is a clever way -- in John Resig's book he talks about it -- it
involves executing the anonymous function right after declaring it, when in
a for loop:
function() { do whatever; }();
But, I tried some experiments and I couldn't get it to work right.

I ended up doing something similar to what you suggest, but I really
was hoping to elicit some clever way to get the value of the variable
at the time of the assignment, rather than the "5" that I get because
the closure is maintaining the context.
Is there a way to set these event handlers up in jQuery without using
a closure?

Instead of binding five times, you can do it dynamically:
$("[id^=port]").click(function() {
bigchart( this.id.charAt(this.id.length-1) );
});
Something close to that should do it. Although if you end up with 10 or
more clickables you'll have to change your naming scheme a bit.
