More information of this pkg-config bug. It is seems to be distro
dependent. The previous note was for the SuSE Linux Enterprise Server
Distro. The problem does not occur on OpenSuse-10.3 because the Gnome
libraries are in different directories.

On OpenSuse pkg-config --libs glib-2.0 gthread-2.0 generates:

	-pthread -lgthread-2.0 -lrt -lglib-2.0

Which is ok, because LDFLAGS=-m64 allows gcc/ld to find the correct

The difference is that on opensuse the Gnome librairies are stored
directly in /usr/lib and /usr/lib64. (vs /opt/gnome/lib64

> find /usr -name 'libglib-2.0*'

This prevents pkg-config from generating the unnecessary
"-L/opt/gnome/lib" option. 

I suspect that for linux the -L option is not required for either case,
given a properly defined ld.so.conf.
