Comment (by beany_kelly@…):

 Mine compiled fine also! Tried to post that a few hours ago, but the
 system wasn't responding.

 Presumably those header ports *were* needed once upon a time, or they
 wouldn't have appeared in our installed ports list.

 Perhaps running

 {{{
 sudo port uninstall leaves
 }}}

 would have avoided this? I'm running it now, but didn't think of checking
 for this functionality before I began composing this update.
