Install Command Line Tools for Xcode
Command Line Tools are required for Homebrew. Previously it was suggested to download Xcode 4, but since the new version doesn't ship the proper gcc compiler for rvm, the command line tools are a better option and then using homebrew to get the gcc compiler. If preferred, install Xcode 4, although this setup doesn't follow that set of instructions.
Really the nicest choice for a terminal on OSX right now, especially with Lion style full screen support.
