So I have been trying to remove and reinstall RoR. Reason for that is, something bothered me the first time I installed it last week but I was just trying to learn it and wanted to remove it as soon as I got the book; Railsspace.<p>And now I am stuck with this:<p>$ gem install bundler

You don't have write permissions into the /Library/Ruby/Gems/1.8 directory.<p>How to solve this? Been googling and figuring it out for the last 4 hours!
