glib-2.0 not found

I am trying to install on Centos 5.2 and received the following error;


No package 'glib-2.0' found

Consider adjusting the PKG_CONFIG_PATH environment variable if you
installed software in a non-standard prefix.

Alternatively, you may set the environment variables LIBGLIB_CFLAGS
and LIBGLIB_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.

So using yum I installed glib2 which ended up in /lib as;

libglib-2.0.so.0@
libglib-2.0.so.0.1200.3*

rlib's ./configure still does not see this lib. I am not certain how  
to nudge it in the right direction.

Thanks...
