Subject: require_gem vs. gem

I am confused, can somebody please explain to me the difference between
these two calls?

I tried some variations below, and the only one that worked was the
obsolete require_gem call.

----------

user@vm0_gentoo /my/path $ irb -r rubygems
irb(main):001:0> require 'activerecord'
LoadError: no such file to load -- activerecord
        from
/usr/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:27:in
`gem_original_require'
        from
/usr/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:27:in `require'
        from (irb):1
irb(main):002:0> exit

----------

user@vm0_gentoo /my/path $ irb -r rubygems
irb(main):001:0> gem 'activerecord'
=> true
irb(main):002:0> ActiveRecord
NameError: uninitialized constant ActiveRecord
        from (irb):2
irb(main):003:0> exit

----------

user@vm0_gentoo /my/path $ irb -r rubygems
irb(main):001:0> gem 'activerecord','=1.14.4'
=> true
irb(main):002:0> ActiveRecord
NameError: uninitialized constant ActiveRecord
        from (irb):2
irb(main):003:0> exit

----------

user@vm0_gentoo /my/path $ irb -r rubygems
irb(main):001:0> require_gem 'activerecord'
(irb):1:Warning: require_gem is obsolete.  Use gem instead.
=> true
irb(main):002:0> ActiveRecord
=> ActiveRecord

----------

Any help you could offer would be appreciated.
