Installing Gtk2.14 -> Problem with ATK

[Carlos Fernandez <mrstvx gmail com>]

Hi, i have installed all the dependencies of gtk2.14 sucesfully except
ATK:

checking for GLIB - version >= 2.0.0... 
*** 'pkg-config --modversion glib-2.0' returned 2.18.0, but GLIB
(2.16.6)
*** was found! If pkg-config was correct, then it is best
*** to remove the old version of GLib. You may also be able to fix the
error
*** by modifying your LD_LIBRARY_PATH enviroment variable, or by editing
*** /etc/ld.so.conf. Make sure you have run ldconfig if that is
*** required on your system.
*** If pkg-config was wrong, set the environment variable
PKG_CONFIG_PATH
*** to point to the correct configuration files
no
configure: error:
*** GLIB 2.0.0 or better is required. The latest version of
*** GLIB is always available from ftp://ftp.gtk.org/.

I use Debian Lenny stable, and i am installing gtk+-2.14.0 from the
source code (and atk, pango, glib...).

Somebody could help me? Thank you very much, I appreciate your help.
