+1. I've been noticing more projects excluding the Gemfile.lock
alltogether in their source repos, and hope this trend continues.

Jayg (cc'd) wrote bundler_ext [1]  (on rubygems here [2]) which is an
extension to bundler to use dependencies that have been installed using
the native system tooling (yum / apt-get / etc)

AFAIK it doesn't install missing packages using yum / apt-get, but
perhaps that could be added (though I'd refer to jay for more info)

+1, see the screencast here [3]
