The version of Ruby that comes with OS X is installed in /usr/bin. The 
version you installed is (probably) in /usr/local/bin. You can confirm 
this by typing

which ruby

Anyway, all you need to do you change your $PATH environment variable to 
make /usr/local/bin precede /usr/bin. If you don't know how to do this, 
read the "bash" man page about the PATH environment variable. (See the 
INVOKATION section.)
