can all of your code run as in

   ./my_code.rb

??

eg.  not

   ruby ./my_code.rb

if not that may be your problem.  when you do

   daemon.rb ./my_code.rb

it's literally going to do

   system './my_code.rb'

at some point.  if your code requires

   system 'ruby ./my_code.rb'

the you'd need to do

   daemon.rb ruby ./my_code.rb
