I am wondering if you can remove the dependency on sqlite

We deploy code to Heroku and Heroku will block our deploy if sqlite is included.

We ran into the same issue. We ended up fixing this by installing stuff-classifier from Git - I believe the version hosted on rubygems is several editions out of date.

Does anyone know why sqlite3 is needed? I'd do the same (install from Git) but for some reason the prediction quality went way down when I tried that. If I had time I'd dig into why the algorithm is different, but if someone happens to know if it's easy to just remove the sqlite3 dependency that would be helpful...thanks!
