Install mysql gem using bundler in ubuntu 11.10 64 bit

Well just tried doing a mysql gem install using bundler (Gemfile) but got an error like this

Gem::Installer::ExtensionBuildError: ERROR: Failed to build gem native extension.

        /home/praveen/.rvm/rubies/ruby-1.9.2-p290/bin/ruby extconf.rb
checking for mysql_query() in -lmysqlclient... no
checking for main() in -lm... yes
checking for mysql_query() in -lmysqlclient... no

and much more

and i forgot to install  libmysqlclient-dev :) how careless! so did
sudo apt-get install libmysqlclient-dev

and redid the bundle install and wohooo it worked!
