I got this error:
sudo gem install mysql2
Building native extensions. This could take a while...

Results logged to /var/lib/gems/1.8/gems/mysql2-0.2.6/ext/mysql2/gem_make.out
I have tried:
- uninstall mysql2 and install it again
- uninstall mysql with apt-get
- installd dev-tools from mysql
- and almost all the pages on Google
How can I fix this?
