installing new libs ,missing libgtk.so.0 and no problem

I tried to install the gnome-xml libs (downloaded from cvs). They compiled fine and installed in usr/local/libs. I added the directory into /etc/ld.so.conf and ran ldconfig. When i tried to compile another program that tried to link into that library i got the message ... -lxml ... linking failed.
