on my FC4 so after the
# yum list "*screensaver*"

xscreensaver-gl-extras.i386              1:4.21-4               base

I did
# yum install "*screensaver*"
I realize that those packages actually weren't on fedora extras repo 
site even when they appears on filelist.xml

Can anybody tell why were they removed from the repo?
