Suse 10.2. How do I fix this?

The currently installed libary is 2.14.1, but I did install 2.12.4

*** 'pkg-config --modversion glib-2.0' returned 2.14.1, but GLIB
*** 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
*** by modifying your LD_LIBRARY_PATH enviroment variable, or by
*** /etc/ Make sure you have run ldconfig if that is
*** required on your system.
*** If pkg-config was wrong, set the environment variable
*** to point to the correct configuration files
