Comment (by kencu):

 clue:
 {{{
  % port provides /opt/local/bin/gtkdocize
 /opt/local/bin/gtkdocize is provided by: gtk-doc
 }}}

 I am not sure why this is showing up lately. There was another port
 recently with the same problem. Obviously something to be sorted out with
 autoreconf and gtk-doc.
