The easy way is just to go to:
<http://ruby-lang.org/en/> and download the latest stable or stable  
snapshot version of Ruby. Build and install it by cding into the ruby  
directory and then doing:

./configure
make
make test
sudo make install

Finally make 3 text files in your home folder that will be invisible  
in the Finder. One will be named .bash_profile and it will contain  
the line:
source .bashrc
The second file will be named .bashrc and will contain:
export CLICOLOR=1
export RI='-T -f ansi'
##
# DELUXE-USR-LOCAL-BIN-INSERT
# (do not remove this comment)
##
echo $PATH | grep -q -s "/usr/local/bin"
if [ $? -eq 1 ] ; then
     PATH="/usr/local/bin:$PATH"
     export PATH
fi

Finally, make a file called .inputrc containing
set completion-ignore-case On


It's a good idea to end each of these text files with a carriage  
return. Some of the above has nothing to do with Ruby per say but it  
does have to do with making unix tools usable on HFS+. Other things  
are more complex than they need to be just for OS X but I find that I  
can carry these files around with me and they work on other unixish  
systems.
