Help with libglademm and i18n

[Fernando Herrero Carrón <fhcarron terra es>]

Hi guys,

I'm trying to load a glade interface with gtkmm and not everything gets
translated as I had hoped.

I have a window with a menu bar, and just one submenu of the "file" menu
gets translated: "New" to "Nuevo" (Spanish).

I've searched a little bit in internet and have found something about
libglade-xgettext, but this is not installed in my system.

I'm using gtkmm-2.4 and libglademm-2.4. Any hints?

Many thanks,

Fernando
