Mongrel not playing nicely with older rails/ruby

I'm trying to transfer an older Rails project to a new server, never
would have thought it would have taken me this long (first time with
Ruby On Rails).

Anyways the site uses Ruby 1.8.4, Rails 1.1.6, gems 0.8.10

I installed Mongrel and Mongrel_Cluster and it prompted me for a
version, I selected the newest.... Now when I try to start Mongrel I
get this error:

** Ruby version is not up-to-date; loading cgi_multipart_eof_fix
/usr/local/lib/ruby/gems/1.8/gems/mongrel-1.1.5/bin/../lib/mongrel/
gems.rb:12:in `require': undefined method `gem' for
Mongrel::Gems:Module (NoMethodError)
  from /usr/local/lib/ruby/gems/1.8/gems/mongrel-1.1.5/bin/../lib/
mongrel.rb:355
  from /usr/local/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:
18:in `require'
  from /usr/local/lib/ruby/gems/1.8/gems/mongrel-1.1.5/bin/
mongrel_rails:11
  from /usr/local/bin/mongrel_rails:18

I know my Ruby version is not up to date... but I don't think I want
to update it for fear of the app not properly working. Should I
install an older version of Mongrel...? If so,.... which version?

Thanks in advance for any guidance or assistance you may be able to
provide.

Looks like what you need is a newer version of Rubygems and not ruby
or mongrel. You can get the latest one here ->
http://rubyforge.org/frs/?group_id=126

Ok, now I get this...? Any clue as to what I'm missing?

that looks like your app is requiring ruby-debug but that the gem
isn't installed
