A probably better option would be to set this as a dependency in the Gemfile: https://bundler.io/v1.12/gemfile_ruby.html
That would ensure that a compatible ruby version is used.
What do you think?

It is a more sophisticated way than simply describing in the document. I didn't know the feature of Bundler. Thank you for the advice.

The attached is a new patch that updates both Gemfile and doc/INSTALL.

Committed the patch.

The ruby directive in Gemfile is supported by bundler 1.12.0 or later. So, r19425 causes the following error when a user runs bundle install if the version of bundler is prior to 1.12.0.

$ bundle -v
Bundler version 1.11.2
$ bundle install

[!] There was an error parsing `Gemfile`: no implicit conversion of Symbol into Integer. Bundler cannot continue.

You can avoid the error by skipping the ruby directive with the following patch. The version of Ruby is not checked if you run an older version of Bundler that does not support ruby directive.
