At Kongregate we just check the gems into our repo under vendor/cache and then run 'bundler install --local' at deploy time.

Here's the docs that describe it:

"While installing gems, Bundler will check vendor/cache and then your system's gems."<and then tries to fetch remotely unless you pass --local>
