Typically you would want to update your system glib using your
package manager (synaptic ?).

If you want to install a tarball by hand in an optional prefix,
thats what you did.

I usually write a simple little script like this to build & test
stuff in an optional prefix:
===============================
PREFIX=/opt/gnome
PATH=$PREFIX/bin:$PATH
LD_LIBRARY_PATH=$PREFIX/lib
PKG_CONFIG_PATH=$PREFIX/lib/pkgconfig

export PATH LD_LIBRARY_PATH PKG_CONFIG_PATH
===============================

And then feeding in /opt/gnome to the --prefix arg of configure.

You should be able to test your glib in /usr/local by simply
typing "LD_LIBRARY_PATH=/usr/local/lib ./myprogram".
