<dtml-if X>
 <a href="a_url">
</dtml-if>
 link text
<dtml-if X>
 </a>
<dtml-else>
 (no link currently available)
</dtml-if>

The annoying things is that X has to be repeated which could be a large
expression. The other option would be 

<dtml-let cache_X="X">
<dtml-if cache_X>
 <a href="a_url">
</dtml-if>
 link text
<dtml-if cache_X>
 </a>
<dtml-else>
 (no link currently available)
</dtml-if>
</dtml-let>

but anyway you look at it its still uglier.
