I always get "Server not found" the first time, but if I repeat it works.

I don't want to "zoom around in spectacular ways" with Watir commands :) ,
I want to debug existing cucumber code failures.

* I couldn't figure out how to get irb to load my PageObject.
* I couldn't figure out how to get irb to run the cucumber command line.

http://www.agileforall.com/2011/12/cucumber-tip-irb-from-inside-a-step-definition/failed
with
    ERROR:  Error installing ruby-debug:
      ERROR: Failed to build gem native extension.
    /home/spage/.rvm/rubies/ruby-2.1.0/bin/ruby extconf.rb
   Can't handle 1.9.x yet

But (good news), the suggestion to use pry-nav in
https://groups.google.com/forum/#!topic/watir-general/fFeBBU6n2jw (where
Zejlko contributed!) worked:

1. add
  gem "pry-nav"
to Gemfile
2. bundle install
3. insert
      require 'pry-nav'
      binding.pry
in the step_definition where I want it to stop.

That helped identify the problem.  But I'm still confused how to
interactively tweak a page element.  I have a definition of a PageObject
element:
    button(:comment_reply_save, class: "flow-reply-submit")
that doesn't work, how can I interactively change it, or try a new one?
The cycle time to modify flow_page only to find that text_input doesn't
support the css class is painful.

Cheers,
