installing ruby-debug-ide on an offline machine

Question

I'm trying to install ruby-debug-ide-0.4.15.gem on an Ubuntu 10.04 machine which is not connected to the Internet, and I get the following errors:

ERROR: Error installing ruby-debug-ide-0.4.15.gem: ERROR: Failed to build gem native extension.

/usr/bin/ruby1.8 mkrf_conf.rb ERROR: http://rubygems.org/ does not sappear to be a repository

Installing the same gem on a similar machine which is connected to the Internet, work fine. What can be the problem?

Thanks.

Because authors of ruby-debug-ide gem are an using extension mechanism not to build some library that was written in C, but to install another gem depending on your Ruby version. This is form ruby-debug-ide's ext/mkrf_conf.rb file:

inst = Gem::DependencyInstaller.new
begin
  if RUBY_VERSION < "1.9"
    inst.install "ruby-debug-base", '>=0.10.4'
  else
    inst.install "ruby-debug-base19", '>=0.11.24'
  end
  rescue
    exit(1)
end

It tries to download and install ruby-debug-base gem.
