Checking through Fenner's distfile logs, several GNOME ports have some out-of-date master sites. In the case of cs.umn.edu/pub/gimp/2.0 and ftp.gtk.org/pub/gtk/2.0, the subdirectory just needs to be 2.2. In the case of ameth.org, some subdirectories have just disappeared. In the case of gtk-doc, the subdirectory was changed long ago (no change to the distfile, however). All of these ports are maintained by gnome@FreeBSD.org. How-To-Repeat: (Fenner's logs)
Responsible Changed From-To: freebsd-ports-bugs->gnome over to maintainers
State Changed From-To: open->closed Committed, thanks!
