po/Makefile.in.in was not created by intltoolize."

I found this really old thread:
https://mail.gnome.org/archives/gtkmm-list/2009-August/msg00072.html

and this really old script to "work around" the issue.

#! /bin/sh -etest -n "$srcdir" || srcdir=`dirname "$0"`test -n
"$srcdir" || srcdir=.(
  cd "$srcdir" &&
  AUTOPOINT='intltoolize --automake --copy' autoreconf --force
--install --verbose) || exittest -n "$NOCONFIGURE" ||
"$srcdir/configure" "$_at_"



Do I just have to implement this in the ports Makefile or is there some
workaround?
