I'm not sure what's going on but try running sudo ruby prog ... When installing gems with sudo ruby probably uses a different directory to store your gems.
Most people here use rvm, rbenv or chruby to get over issues with sudo and use ruby at user-level.

You should try one of these, to get through these annoyances once and for all.

Note that in order to install sqlite under ubuntu you need sqlite headers.

Best Regards,

ps. I use rvm but people at #ruby@freenode talk a great deal about rbenv you should try it https://github.com/sstephenson/rbenv
