that is correct.

and that is correct too. 

equery belongs /usr/lib64/opengl/xorg-x11/extensions/libglx.so
 * Searching for /usr/lib64/opengl/xorg-x11/extensions/libglx.so ...
x11-base/xorg-server-1.6.1.901-r4 (/usr/lib64/opengl/xorg-
x11/extensions/libglx.so)

mesa does not install any libglx files.
