Vague question, and you should probably pull up a tutorial to walk you through the process if you're not sure how to do this yet, but…

tar -xzf ruby_1.9.2.tar.gz
cd ruby_1.9.2/
./configure
make && make install

Might I suggest using RVM instead? It'll handle installing ruby, and let you manage and switch between different rubies and gem sets for each application. It's really easy to get started with, too. Check it out:

if you are on ubuntu, you can use apt to install ruby1.9.2

sudo apt-get install ruby1.9.1-full

check your install

ruby1.9.1 -v

it will return ruby 1.9.2-p0.

edit your .bashrc , back to normal.

alias ruby="ruby1.9.1"
alias irb="irb1.9.1"
alias gem="gem1.9.1"

everything will be allright.
