Can't install sqlite3-ruby gem to work with rails 3

Hello everyone , I just installed Rails 3 and I'm aiming to play with it. But when I try to install the sqlite3-ruby gem I get this message. I use Ubuntu Karmic, have sqlite installed and use Ruby Enterprise Edition.

ubuntu% gem install sqlite3-ruby Building native extensions. This could take a while... ERROR: Error installing sqlite3-ruby:   ERROR: Failed to build gem native extension.

/home/rodrigo3n/.rvm/rubies/ruby-1.9.1-p378/bin/ruby extconf.rb checking for fdatasync() in -lrt... yes checking for sqlite3.h... no *** extconf.rb failed *** Could not create Makefile due to some reason, probably lack of necessary libraries and/or headers.

thanks.

you may be missing the sqlite3 dev package, try:

sudo aptitude install libsqlite3-dev

Thank you, it works now!
