Rails - Jun 2008 - Any thoughts on building a project using an old version of rails?

I am trying to build some sample projects from the book "Ajax on
Rails." These projects are built against Rails 1.1.5, I am using Rails
2.0.2.

The directions are to copy the sample code to your code folder, add
all the default rails files, and then edit config/database.yml.

So I installed the rails 1.1.5 gem, and then added the default files
with

# rails _1.1.5_ -s photo_gallery

But then script/server won''t work. It ran into two occurrences of
"require_gem" that seem to now need to be "require" in
boot.rb. I
changed those lines, and now I get

# script/server
/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/
1.8/rubygems/custom_require.rb:27:in `gem_original_require'': no such
file to load -- rails (LoadError)
        from /System/Library/Frameworks/Ruby.framework/Versions/1.8/
usr/lib/ruby/1.8/rubygems/custom_require.rb:27:in `require''
        from ./script/../config/boot.rb:38
        from script/server:2:in `require''
        from script/server:2

And, for what it is worth, I can''t seem to freeze rails into this
project or even into a new project. When I try

# rails _1.1.5_ -f test_frozen

it generates all the rails files, but then when it tries to freeze the
code I get the error message

/Library/Ruby/Gems/1.8/gems/rails-1.1.5/bin/rails:19:in `chdir'': No
such file or directory - -f (Errno::ENOENT)
        from /Library/Ruby/Gems/1.8/gems/rails-1.1.5/bin/rails:19
        from /usr/bin/rails:19:in `load''
        from /usr/bin/rails:19

Is it just impossible to run an old version of rails?

If the answer is yes--then perhaps there is more modern example code
that will allow me to experiment with script.aculo.us and JavaScript?
Pointers?

Thanks

The replacement for require_gem is gem

Thanks Frederick, that was the help I needed.

For anyone who stumbles across this post, a recipe for building
"Example B: Photo Gallery" from "Ajax on Rails" by Scott
Raymond is

download and unzip the archives from the book
copy the code from "Photo Archive" to a folder named
"photo_archive" (for convenience)
install rails 1.2.5 you don''t have it (gem install rails -v=1.2.5)
install the standard rails files in photo_archive (rails _1.2.5_
photo_archive -s)
change "require_gem" to "gem" in two places in
config/boot.rb
change RAILS_GEM_VERSION to ''1.2.5'' in config/environment.rb
configure the database and make an sql database if you need to
run two rake tasks: rake rails:update; rake db:schema:load

For whatever reason, it wouldn''t build against rails 1.1.5 which it
says it wants

Again, thanks

A
