Safely require gems in Ruby

Is there a way to require a ruby gem safely so as to not raise an exception if the gem is not found?

I am looking a solution close to this:

if require 'hirb'
  # do some hirb related stuff
else
  # do other stuff
end

I want this to make sure no unnecessary gems are failing my deploys to production.

The best way to do this is to use bundler, that way you can be sure your gems really will be installed.

It would probably be done like this:

begin
  require 'hirb'
rescue LoadError => e
  puts "could not find hirb"
end
