I personally like to pass the third (optional) comparison param to  
version_compare().  When you do this, version_compare() returns true/ 
false (instead of the confusing -1, 0, 1).  No benefit other than  
readability.

<?php
global $wp_version;
if ( version_compare($wp_version, '2.1', '<') )
	die('Your version is too low!');
?>

Note that the direction of the comparison param is just as if it were  
moved to the left, inbetween the first and second param.
