On the latest Ubuntu (11.10) there is also an issue with readline.

Readline was unable to be required, if you need completion or history install readline then reinstall ruby.

So my entire rvm and latest ruby install process for ubunutu 11.10 was:

# install rvm
sudo apt-get install curl
curl -L get.rvm.io | bash -s stable

# install dependencies
rvm pkg install zlib
rvm pkg install readline

# install additional dependencies -- follow instructions for your distribution/version
rvm requirements

# install ruby
rvm install [ruby-version]

I'm posting this for my future reference and in case anyone else bumps into this issue as well.
