You have two versions of glib and gtk+ (and probably other libraries
such as pango, cairo and atk) installed on your system and the old
version, presumably in the /usr prefix, is being picked up by the
dynamic loader instead of the one you have placed in the /usr/local
prefix.

The best thing is not to go down this route at all, and to install your
updated libraries by building them as RHEL packages which replace your
existing ones. If however you insist on having two different versions of
the same libraries installed on your system you might want to google
for the LD_LIBRARY_PATH environmental variable.
