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. Check the mkmf.log file for more
details. You may need configuration options.

Provided configuration options:
–with-opt-dir
–without-opt-dir
–with-opt-include
–without-opt-include=${opt-dir}/include
–with-opt-lib
–without-opt-lib=${opt-dir}/lib
–with-make-prog

Gem files will remain installed in /home/rodrigo3n/.rvm/gems/
ruby-1.9.1-p378/gems/sqlite3-ruby-1.2.5 for inspection.

you may be missing the sqlite3 dev package, try:

sudo aptitude install libsqlite3-dev
