I guess it depends how much is really different in 1.8.7. For example, I 
really, really like Object#tap -- started using it in 1.9, and I see it's now 
in 1.8.7. But at work, we use 1.8.6. My solution:

unless Object.new.respond_to? :tap
  Object.class_eval do
    def tap
      yield self
      self
    end
  end
end

The "unless" is because, of course, both 1.8.7 and 1.9 write this method in C, 
and I assume their version is faster than mine.

I'd be much more concerned if there was 1.8.6 code that didn't run properly in 
1.8.7, which I think is what started this discussion.
