xscreensaver-demo does not list the hacks in rss-glx package

I have installed the rss-glx package in my Suse Tumbleweed system, and I can see the binaries in /usr/bin/ (the binaries work flawlessly), the symbolic links from /usr/lib64/xscreensaver/ to the binaries, and the corresponding XML files in /etc/xscreensaver/. What I don't see are the new hacks in the list provided to me by xscreensaver-demo! Here it is one of those XML files $ cat /etc/xscreensaver/pixelcity.xml Procedural city fly through. Written by Shamus Young . Ported to Linux by Tugrul Galatali - . and the associated paths in the binaries directories /usr/bin/rss-glx-pixelcity /usr/lib64/xscreensaver/rss-glx-pixelcity I can see two issues, 1. no reference to the actual binary name in the XML file 2. the symbolic links to rss-glx binaries are in /usr/lib64/xscreensaver/ but XScreensaver binaries are in a different place, /usr/libexec/xscreensaver/. I don't know what to do, what should I do?
