Problems with RVM installing Ruby?

Question

I'm trying to install Ruby using RVM on a Macbook Pro running Mavericks. I'm a little over my head, but whenever I type in rvm install 2.1 it fails and gives me the following error:

Error running 'requirements_osx_brew_update_system ruby-2.1.1',
showing last 15 lines of /Users/ianvshuff/.rvm/log/1396019921_ruby-2.1.1/update_system.log

and make sure `brew update` works before continuing.'

Requirements installation failed with status: 1.

Xcode is installed and everything. Anyone know what's going on?

It looks like RVM is trying to install some requirements by using Homebrew, which is not installed or configured correctly. You can install Homebrew, or type rvm requirements and try to resolve them manually.
