Subject: Installing mySql GEM on Ubuntu?

I am running Linx Mint, a version of Ubuntu, and I installed Ruby
and Rails. However, when I try to install the mySql package via. gem, "gem
install mysql" I get an error message (See below) with no idea how to fix
the error.  I looked on the net (Google), but all suggestions do not work
with this Linux.

Also, as far as I know, I have all of the correct mySql drivers/headers,
etc.

=================== error message  ==================================

Select which gem to install for your platform (i486-linux)
 1. mysql 2.7.3 (mswin32)
 2. mysql 2.7.1 (mswin32)
 3. mysql 2.7 (ruby)
 4. mysql 2.6 (ruby)
 5. mysql 2.5.1 (ruby)
 6. Cancel installation
