I'm running into some weird issues related to anything that relies upon DocBook 4.1.2.  I've seen this on a couple of other ports, but I will use gtk-doc as the example.  'sudo port install gtk-doc' results in:
<div>&nbsp;</div><div><b>&lt;snip&gt;</b></div><div>---&gt;&nbsp; Configuring gtk-doc</div><div>Error: Target com.apple.configure returned: configure failure: shell command &quot; cd &quot;/opt/local/var/db/dports

</div><div>&nbsp;</div><div>Also, I see that there is a &#39;docbook-xml-412&#39; port as opposed to &#39;docbook-xml-4.1.2&#39; but it&#39;s info says it is depreciated so I&#39;m assuming I shouldn&#39;t be using that.
