Answer 1

if you have not installed mysql try adding the following full packages:

sudo apt-get install mysql-server mysql-server-5.1 libmysql-ruby libmysqlclient-dev mysql-client-5.1 mysql-common

Also checkout this heroku db:pull cant connect to my DB in ubuntu

Answer 2

This should solve your problem

sudo apt-get install libmysqld-dev libmysqlclient-dev mysql-client

gem install mysql2
