Mac OS X is bundled with ruby and rails, however they are not up-to-date.

10.6.6 versions:

I followed the excellent guide at spyrestudios to bring me up to speed on my ruby environment - including updating ruby+rails to the latest builds.

MacPorts:

After installing macports, run: sudo port -v selfupdate

For exploring the available packages run the list command on port interactive mode.

I also found it useful to install sqlite3: sudo port install sqlite3

RVM:

Run: bash < <( curl http://rvm.beginrescueend.com/releases/rvm-install-latest )

Place the following line in your ~/.profile:

[[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm" # This loads RVM into a shell session.

For exploring RVM, run: rvm list known

To update ruby run the following

Check out: http://rvm.beginrescueend.com/rubies/default/ to set the default ruby and to switch between 1.9.2. and system ruby.

Rails:

rvm use –-create 1.9.2@rails3
gem install sqlite3-ruby
gem install rails
