$ bash -s stable < <(curl -s https://raw.github.com/wayneeseguin/rvm/master/binscripts/rvm-installer)
$ echo ' -s "$HOME/.rvm/scripts/rvm"  && . "$HOME/.rvm/scripts/rvm" # Load RVM function' >> ~/.bash_profile
$ source ~/.bash_profile

Ruby

$ rvm install 1.9.2
The provided compiler '/usr/bin/gcc' is LLVM based, it is not yet fully supported by ruby and gems, please read `rvm requirements`.
