It was Ivan's answer that tipped me off.

In addition to declaring the iruby and nyaplot gems, you need to declare the appropriate ZeroMQ interface.

So, in your Gemfile,

gem 'iruby'
gem 'nyaplot'
gem 'rbczmq' # or 'ffi-rzmq'
# any other gems you want to use should go here too

Alternatively, if you're working on a project with a gemspec, you need the following two lines in the spec:

gem.add_development_dependency 'iruby', '~>0.2'
gem.add_development_dependency 'rbczmq'

And also one for nyaplot if that's what you're using.
