If people havent figured it out and still get the space between the blocks, here's wut u do...
in pagenav_pagelink, u should have...
Code:
<span class="pagenum"><a href="$address&pagenumber=$curpage">$curpage</a></span>
Well replace it with...
Code:
<span class="pagenum"><a href="$address&pagenumber=$curpage">$curpage</a></span> 
It should work, it worked for me.
