System Upgrade

Okay, here I am trying to solve the crashing in my Arch(bang) Linux crash and I think it might be the openGL crashing it. I ran "sudo pacman -Syu" and it gives me the following (Pastebin link) http://pastebin.com/66ndxW6K. On a side note for some reason I can't install Skype in Arch. It wont let me let me install lib32 files needed for Skype, any idea on what to do.
