I am trying to install Ruby 1.9.2 on a brand new MacBook Air with OSX Lion (10.7.2) and I keep getting an error message during the installation process. I’m new to Ruby and starting out with Ruby on Rails 3 Tutorial, so I downloaded RVM and then ran the command “$ rvm install 1.9.2.” and this is what happened:

Any help or alternative solutions would be greatly appreciated. And since I am new to this, please let me know if I need to provide more info.
Thanks!
UPDATE: here is the info from the configure log:

See `config.log' for more details
Does this mean I need to download a C compiler (e.g. XCode?)
UPDATE (2): Problem solved by downloading Xcode!
error: no acceptable C compiler found in $PATH
well, you don’t have the Xtools development kit installed on your Mac! e.g. there is no C compiler…
you should pop-in that OS X DVD or the Flash Drive which came with your computer, and install Xtools,
and after that try to install Ruby again..
