I get the following error message

C:/InstantRails/ruby/lib/ruby/site_ruby/1.8/rubygems.rb:251:in
`report_activate_error': Could not find RubyGem activerecord (>=
0.0.0) (Gem::LoadError)
	from C:/InstantRails/ruby/lib/ruby/site_ruby/1.8/rubygems.rb:188:in

	from C:/InstantRails/ruby/lib/ruby/site_ruby/1.8/rubygems.rb:59:in
`require_gem'
	from C:/RadRails/workspace/album/my_ruby_code.rb:1

When I try execute the following piece of code

require_gem "activerecord"

class Photo < ActiveRecord::Base
end

Photo.establish_connection(
  :adapter => "mysql", :database => "album_development")

for column in Photo.columns
  print column.name, "\t"
end

puts
puts

for photo in Photo.find(:all)
  for column in Photo.columns
    print photo.send(column.name), "\t"
  end
  puts
end

I suspect it's a class path problem or a bug in the version I am using
which is the 1.8.4 stable version

If anyone can help, i'd really appreciate it.

Thanks
