Getting emacs realgud:pry to work - emacs

Question

Need some help getting realgud to play nice with pry-remote.
This is a sample ruby file (x.rb)
require 'pry-remote'
class Foo
def initialize(x, y)
binding.remote_pry
puts "hello"
end
end
Foo.new(1,3)
In a shell buffer:
bash: ruby x.rb
[pry-remote] Waiting for client on druby://127.0.0.1:9876
# check that I have a listening process
bash: ss -nlt
State Recv-Q Send-Q Local Address:Port Peer Address:Port
LISTEN 0 128 127.0.0.1:9876 *:*
In emacs:
M-x realgud:pry
pry-remote ; enter this at the prompt
This is what I see in emacs;

My question is: why am I seeing the breakpoint in tracer.rb? How do I get the breakpoint
to be in my source file?
Hitting 'n' twice in the source window causes the shell buffer to echo the following, but there
is no change in the source window itself.
=>[0G[1] pry(#<PryNav::Tracer>)> next 1
next 1
Also, the 'u' and 'd' keystrokes yield
