In other words, your system's ruby software is called 'ruby', and the 
ruby software you just installed is called 'ruby1.9'.  To check the 
version of the program named 'ruby1.9':

$ ruby1.9 -v

and to run your ruby programs you have to type:

$ruby1.9 your_program.rb

The easiest thing to do is set up an alias for 'ruby1.9', e.g. 'r'.
Then you can run your programs with less typing, like this:

$r your_program.rb

or check the version like this:

$r -v

It's my understanding that Terminal checks the file ~/.bash_profile
before starting up, so you can put your aliases in there.  If the file 
doesn't exist (and it probably won't) then create it.  The 
~/.bash_profile file is where I have my PATH set:

export PATH=/Users/me/Downloads/rails_downloads/MacVim-7_3-53:$PATH

and at the bottom of the file I have the line:

source ~/.bashrc

which I think makes Terminal also read what's in the file ~/.bashrc
before starting up.  I actually  have my aliases in .bashrc.

If you need a good editor, spend a few minutes learning vim by typing:

$vimtutor

If you like what you see, then you can install Macvim and the vividchalk
colorscheme for a great combo.
