cannot load such file -- restclient/instrumentation

While adding instrumentation tracing to my existing app, I got the error cannot load such file -- restclient/instrumentation

Here's the bulk of the stack dump:

% bundle exec rails console 
cannot load such file -- restclient/instrumentation

Add the restclient-instrumentation gem to Gemfile:

gem 'restclient-instrumentation'

...and then run bundle install, as described in https://github.com/opentracing-contrib/ruby-restclient-instrumentation#installation
