This is with the sequel-3.48.0, sqlite3-1.3.7 and omf_oml 0.9.7 gems.

It is worth noting, however, that the web interface is up and running, but no data is displayed.

Run the 'demo' example. Lots of stuff has changed and I haven't kept up with keeping the examples going.

ruby -I lib -I ../omf_oml/lib example/demo/demo_viz_server.rb --print-options start

Make sure you use ruby1.9
