Ruby on Rails

Hello,

I had the same problem for a long time, and every forumtopic was quite
old, only solved for Ruby1.8+Rails2.3.X. Finally I solved this way:
installed RVM, with that I upgraded to Rails 3, set Ruby1.9 as
default, then:
gem install sqlite3,

and in the Rails app I created, in the Gemfile:
gem 'sqlite3-ruby', :require =>'sqlite3'
then bundle install, update... you will find your way.

Anyway may I ask your Ruby, Rails, Gem versions, and which OS you use?
Feel free to write me private if it still doesn't want to work.
Cheers,
Zoltán
