Urgently? If you need it that bad, then you can do the "simple" thing by going online, searching for snort, and seeing that on their web page, you can download the source. Why you would go through the trouble of registering an account on LQ just to ask this question is beyond my thinking skills, as the easiest way to find out is to search using google, yahoo, etc. And why so urgent? Is this part of a homework assignment? If so, then one thing left to say..... We are here voluntarily, therefore, we are not doing your homework for you.
Thank you for understanding, and wish the best of luck to you.
