Its in the tarball, but current versions are out of date for the catalog DTD
(I've actually never used it...) but someone has written a patch against
the current DTD here http://bugzilla.gnome.org/show_bug.cgi?id=578465,
which just needs a little work since it defines an ordering of tag which
is not mandatory (with an updated DTD, I'll introduce it to our Makefiles
so that our catalogs get validated at build time).

If you are creating custom virtual properties by way of the catalog
(i.e. in the case you may be faking a class purely by catalog without
loading the actual widget type into Glade), then please look at
plugins/gtk+/gtk+.xml.in for better examples, we have better support
for that now but I havent yet brought the docs up to date in that respect.

Do you have Glade headers and pc files installed ? if you built from sources;
where did you install Glade ? if you installed Glade in /opt for instance,
you will need to set PKG_CONFIG_PATH=/opt/lib/pkgconfig:/usr/lib/pkgconfig

Alternatively you can just set GLADE_CATALOG_PATH=~/catalogs when
firing up Glade and it should pickup any catalogs you put in ~/catalogs
