If I change the version of bundler required in a Gemfile, and then type bundle, I get

Bundler could not find compatible versions for gem "bundler":
  In Gemfile:
    bundler (>= 1.10.2) ruby

  Current Bundler version:
    bundler (1.9.9)
This Gemfile requires a different version of Bundler.
Perhaps you need to update Bundler by running `gem install bundler`?
Could not find gem 'bundler (>= 1.10.2) ruby in any of the sources

Is it possible to ask bundler to install the new version of bundler, rather than typing in gem install bundler?

Seems like bundler can't bundle itself :)

So you have to run gem install bundler.
