Rails - Feb 2006 - require ''digest/md5'' not working on Mac or Windows

I''ve tried the following line in ruby script/console

require ''digest/md5''

Both my Mac (Intel iMac) and my Windows box return "false"...  Any
ideas
what could be wrong?  I was trying to do the RoR Recipe on page 54 of 
Chad Fowler''s new (beta) book.

Just make a note, I am aware I can just use SHA1 very easily instead, 
I''m just curious why MD5 doesn''t work.

I had that problem too...I think you could probably just substitute sha1
for md5

digest/md5

and elsewhere SHA1 for MD5

and for what it''s worth...I thought that particular recipe was
''half-baked'' since it offered not even the slightest example
of view
code that you could use to make that work and I spent too much time
grappling with it and abandoned it for another time.

I saw ''ext/digest/md5'' in ruby 1.8.2 sources.
You can try to build and install md5 from the source.

Nothing is wrong.

$ ruby
p require ''digest/md5''
-:1: warning: parenthesize argument(s) for future version
p require ''digest/md5''
-:2: warning: parenthesize argument(s) for future version
true
false

I suppose I should also mention:

$ ruby
require ''no such file''
-:1:in `require'': no such file to load -- no such file (LoadError)
         from -:1

Try
require ''md5''

It''s in a different directory on one of my systems...

No, you need to read more carefully.

Try:
$ ri require
--------------------------------------------------------- Kernel#require
      require(string)    => true or false
------------------------------------------------------------------------
      Ruby tries to load the library named _string_, returning +true+ if
      successful. If the filename does not resolve to an absolute path,
      it will be searched for in the directories listed in +$:+. If the
      file has the extension ``.rb'''', it is loaded as a source
file; if
      the extension is ``.so'''', ``.o'''', or
``.dll'''', or whatever the
      default shared library extension is on the current platform, Ruby
      loads the shared library as a Ruby extension. Otherwise, Ruby  
tries
      adding ``.rb'''', ``.so'''', and so on to
the name. The name of the
      loaded feature is added to the array in +$"+. A feature will  
not be
      loaded if it''s name already appears in +$"+. However, the
file
name
      is not converted to an absolute path, so that ``+require
      ''a'';require ''./a''+''''
will load +a.rb+ twice.

         require "my-library.rb"
         require "db-driver"

require returns false if the file is already loaded.
