sci-visualization/amide gnome dependencies missing ?

[canoine]

Hello,

I met these errors when trying to install amide :

checking for
	glib-2.0	>= 2.16.0
	gobject-2.0	>= 2.16.0
	gtk+-2.0	>= 2.16.0
	libxml-2.0	>= 2.4.12
	libgnomecanvas-2.0 >= 2.0.0
... no
configure: error: Package requirements (
	glib-2.0	>= 2.16.0
	gobject-2.0	>= 2.16.0
	gtk+-2.0	>= 2.16.0
	libxml-2.0	>= 2.4.12
	libgnomecanvas-2.0 >= 2.0.0
) were not met:

No package 'libgnomecanvas-2.0' found

and

checking for
		gnome-vfs-2.0   >= 2.16.0
   ... no
configure: error: Package requirements (
		gnome-vfs-2.0   >= 2.16.0
   ) were not met:

No package 'gnome-vfs-2.0' found

Once gnome-base/libgnomecanvas and gnome-base/gnome-vfs installed, no problem anymore.
