Which versions are you running? FWIW, I'm using

  glade 3.8.0-0ubuntu1
  libglade2-0 1:2.6.4-1build1
  libgladeui-1-11 3.8.0-0ubuntu1
  python-glade2 2.22.0-0ubuntu1.1

and it's libgladeui-1-11 that provides my libgladepython.so. Squeeze's
ought to work, hopefully, or you could grab natty's 3.8 version and
try to build that.

With the fact that glade 3.8 is the last stable gtk2-supporting
version of glade, and glade 3.10 is the first stable gtk3, we may want
to move on gtk3 support sooner rather than later. Maxy, Jon: what do
you think?

You're supposed to be able to install them side by side: presumably
that's what happening here for the upcoming stable releases:

  http://packages.debian.org/libgladeui  wheezy: libgladeui-1-9 & libgladeui-2-0
  http://packages.ubuntu.com/libgladeui   oneiric: libgladeui-1-11 &
libgladeui-2-0

Hopefully we could get a glade-loaded main UI into master and use that
as a way of having to touch less code during our own gtk2 → gtk3
transition. But I think I'd like to do some testing first to see
whether GtkBuilder XML files can be reused across GTK versions or
migrated automatically, and whether the implied promise of those
multiple versions actually holds within a glade 3.10 shell. The
windows of opportunity align, hopefully :)

Yep. At the moment I'm just wrapping up individual widgets to see
what's needed (and because it's quite simple to do). I'm thinking we'd
start by GtkBuilder-ifying the main UI, loading it up front, then
moving the "window" module loader outside gui/layout.py but leaving
each module to init itself at first. Later on the sub-modules can
maybe use some interface to expose their gui XML to the central
GtkBuilder instance and get their callbacks bound into their own
namespace.

BTW, splitting out the custom widgets and making them testable in a
standalone faction seems to be the right pattern during gladeifying,
and it's probably a good thing for the overall health of our code too
:)
