OK, I am answering your question in this way:
I want to keep using the opensource ati drivers. Also I want to use
lib32-libgl for all the 32-bit packages. So as you told me I tried to
uninstall catalyst-utils and lib32-catalyst-utils. But I can't uninstall
these as they aren't installed. So why the hell am I asked to replace
lib32-libgl with lib32-catalyst-utils everytime I upgrade? It is some
sort of a bug? What is causing this problem?
