configure detects two versions of glib (?)

[Raimund Eimann <raimund cs auckland ac nz>]

Hi,

I get an error when I try to run gtk-2.3.2's configure script:

checking for GLIB - version >= 2.3.2...
*** 'pkg-config --modversion glib-2.0' returned 2.3.2, but GLIB (2.2.3)
*** 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 2.3.2 or better is required. The latest version of
*** GLIB is always available from ftp://ftp.gtk.org/pub/gtk/.

I'm not aware of ever having installed version 2.2.3. I know for sure that 
I've got glib-2.3.2 installed in /usr/lib/glib-2.0/

How can I fix this problem?

How can I find out if there is aome other version installed, so that I can get 
rid of it?

Cheers,
Raimund
