I keep getting errors about libxml2.2.dylib being the wrong architecture, and it won't let me open several applications, including Pages, which I need TODAY. So I'm guessing that I need to reinstall the Developer Tools, but the installer hangs after I press "Install" on the "This will take 2.54gb of space" screen. It just hangs there and doesn't do anything. On top of that, when I enter the Terminal, it just says "Process Completed" and doesn't even give me a prompt. If I try the x11 prompt, it doesn't let me gain root priveleges, so I can't uninstall libxml2 or libxslt (which I installed today). I need help on this right now.
