javascript: console.log not working in this context?

(function( $ ){ $.fn.openlayers = function( mapElementId, options ) {
        alert(console.log);
        console.log(options);
        ...
    }
});

Im trying to extend functionality in a javascript library, but much to my suprise, when i got started i realized that nothing was being logged by console.log.. I know that the code is being executed due to the alert() firing properly. However the returned response from the alert function seems to be "function(){}", is that correct? or is in fact console.log and empty function?

So any clues on what's going on here, and why console.log isn't working?

I think i might have found the culprit. Im working with a OpenLayers javascript file, and i can see that their library sets 

OpenLayers.Console={log:function(){},...

However, this is uppercase Console, but maybe that doesn't make a difference? I also have to be in the OpenLayers scope, which i can't really see that i am. So i'm still a little baffled. But it would explain why i'm seeing an empty function

This is the output i get from typing "console" in the debug window of chrome after loading the application where this error occurs.

assert: function (){}
count: function (){}
debug: function (){}
dir: function (){}
dirxml: function (){}
error: function (){}
group: function (){}
groupEnd: function (){}
info: function (){}
log: function (){}
profile: function (){}
profileEnd: function (){}
time: function (){}
timeEnd: function (){}
trace: function (){}
warn: function (){}
__proto__: Object

So it would seem that something, possibly the openlayers javascript is overriding the native console.

Add the following line before OpenLayer script to tell it not to override the console functions.

<script type="text/javascript">
    console.firebug=true;
</script>
