Where to find libglitz-glx.so.1 & libglitz.so.1

[Gayal]

i was installing xgl, and to proceed with
xorg-x11-server-Xgl-1.1.99.1-3.i386.rpm there are 2 dependencies asked prior
to installation.

libglitz-glx.so.1 is needed by xorg-x11-server-Xgl-1.1.99.1-3.i386
        libglitz.so.1 is needed by xorg-x11-server-Xgl-1.1.99.1-3.i386

And i cant find the above. Only thing which is there is ;

glitz-glx-0.5.6-3.fc5.i386.rpm
glitz-0.5.6-3.fc5.i386.rpm

I ve done the installation according to
http://fedoraxgl.tuxfamily.org/index.php?title=Installation_en
So my conclusion is fedora manual cannot be followed all the time???
is it so??
