Project dependencies not showing

Hi. I'm running intelliJ Idea v12.0.4 and trying to create my first rails project.

I installed the Ruby plugin, and started a project thorugh the windows command prompt, and when I set up the new project, I pointed the ruby sdk to the ruby.exe file here: C:\RailsInstaller\Ruby1.9.3\bin

Now under External Libraries I see all gems installed (seemingly ot even dependant ones), but some of the gems that ARE dependant through my gemfile (and installed with bundler) are not in that list. Why not?

Thank you for your help!

Idea 12.0.4

Ruby 1.9.3.

Rails 3.2.13
