I am not sure whether I need any 32-bit libraries, although I do have multilib enabled, but I wonder about those emul-linux-x86 packages. Any way for me to tell what is going on here such as dependencies on 32-bit libraries? -- = Your life is like a penny. You're going to lose it. The question is: How do you spend it?
