Can't build Glade-2 apps

[David Dawson <beagle7@pacificcoast.net>]

I have Glade and Glade-2 and am just learning the system.
I have found that I cannot build anything under Glade-2.

I am getting the following sorts of errors from the make after the ./autogen
is run. (I haven't listed them all):
in file included from /usr/include/gtk-2.0/gdk/gdkcolor.h:4,
                 from /usr/include/gtk-2.0/gdk/gdk.h:30,
                 from /usr/include/gtk-2.0/gtk/gtk.h:31,
                 from main.c:10:
/usr/include/gtk-2.0/gdk/gdktypes.h:32:18: glib.h: No such file or directory

These headers DO exist and I have glib-1.2 and glib-2 installed.

My system is Debian Sarge, up-to-date and I am running a 2.4.23 kernel which
I compiled from source.

I am running Glade and Glade-2 under KDE.

programs built under Glade build, but ones built under Glade-2 don't.

I'd appreciate any suggestions as to how to fix this.

If I left out any crucial information please gently tell me so and I will
supply it.

Thanks
