Maybe you're confusing "last post" with "first unread"? The "first unread" link looks like this:

<vb:if condition="$show['gotonewpost']"><a href="{vb:link thread, {vb:raw thread}, {vb:raw pageinfo_newpost}, 'threadid', 'threadtitle'}" id="thread_gotonew_{vb:raw thread.realthreadid}"><img class="gotonewpost" src="{vb:stylevar imgdir_button}/firstnew.png" alt="{vb:rawphrase go_to_first_new_post}" /></a>
</vb:if>

(that is, you should have pageinfo_newpost in there instead of just pageinfo).
