problem with pangox - and also with pkg-config !

[Alain D'eurveilher <deurveia esiee fr>]

 Hi all,

I'm trying to install GTK2.2.4 on my woody, and i already install the
demendencies requiered, and glib, atk, pango. Now, running ./configure
of gtk, I've got :
<-----
configure: error: pangox Pango backend is required for x11 target
        ----->
I've made a google search on my problem, and i've found a post with :
"(...) Try running 'pkg-config --list-all' and see what pango
packages it lists."
but i have :
<-----
% pkg-config --list-all
Package gtk+-2.0 was not found in the pkg-config search path.
Perhaps you should add the directory containing `gtk+-2.0.pc'
to the PKG_CONFIG_PATH environment variable
Package 'gtk+-2.0', required by 'gnome-window-settings-2.0', not found
        ----->
ok, I'm trying to install gtk2.2.4, and i don't have the 2.0 verison.

And where could I find the PKG_CONFIG_PATH ???

Thanks in advance...
Alain.
