the_author_description not working in 2.0

Can anyone tell me what I need to do to get the author description to show up in 2.0?

I’ve tried using the the_author_description() function as well as

<?php
if(isset($_GET[‘author_name’])) :
$curauth = get_userdatabylogin($author_name);
else :
$curauth = get_userdata(intval($author));
endif;
echo $curauth->user_description;
?>

nither are working in 2.0
