The bundled mysql.rb driver has been removed from Rails 2.2

So.. been trying to get a legacy rails app working and had this error..

after googling for a while, most people got this fixed using a gem install mysql -- --with command, or by copying an installed dll to the ruby bin directory.

However, what fixed it for me was:

sudo apt-get install libmysql-ruby

if you stumbled upon this, i hope it helped!
