Trying this locally, this is what I get:

$ ruby -d -e 'puts "hello,world"'
Exception `LoadError' at
/home/tamara/.rvm/rubies/ruby-1.9.3-p392/lib/ruby/site_ruby/1.9.1/rubygems.rb:1073
- cannot load such file -- rubygems/defaults/operating_system
Exception `LoadError' at
/home/tamara/.rvm/rubies/ruby-1.9.3-p392/lib/ruby/site_ruby/1.9.1/rubygems.rb:1082
- cannot load such file -- rubygems/defaults/ruby
hello,world

$ ruby -e 'puts "hello,world"'
hello,world

So, it's not a 2.0 problem. It may not be a problem at all, as all -d
is doing is setting the $DEBUG global to true, AFAICT. (If you're
expecting that to launch in debug mode, that won't do it. Try pry
instead.)
