Rails - Feb 2013 - How do you download a file from the web and save it locally?

I''m trying to learn Ruby.  A task I''m trying to do is download
a file from
the web and save it locally.

I''m looking at http://ruby.bastardsbook.com/chapters/io/ and trying to 
implement the solution in the "Exercise: Copy Wikipedia''s front
page to a
file using block notation" section, but it''s not working for me. 
The error
message I get is:

/home/jhsu/.rvm/rubies/ruby-1.9.3-p385/lib/ruby/site_ruby/1.9.1/rubygems/custom_require.rb:36:in
`require'': cannot load such file -- rest-client (LoadError)
    from 
/home/jhsu/.rvm/rubies/ruby-1.9.3-p385/lib/ruby/site_ruby/1.9.1/rubygems/custom_require.rb:36:in
`require''
    from test.rb:4:in `<main>''


What am I missing?  Would another approach be better?

Did you install the rest-client gem?

gem install rest-client

You you don''t have the gem installed Ruby can''t very well load
it.
Usually when you see that custom_require it assumes the name you gave in 
require statement is custom since it wasn''t found in the list of gems.
