You are missing the headerfiles for MySQL. If you re on a binary
distribution, "apt-get install mysql-dev" or "yum install mysql-dev"
should make the gem install work (adjust the installation command to
your distribution of *NIX of choice, of course).

Though the folk I have met,
(Ah, how soon!) they forget
When I've moved on to some other place,
There may be one or two,
When I've played and passed through,
Who'll remember my song or my face.
