Subject: RAILS can't load Digest::MD5

Hello-

I was trying to setup Rails for the first time following the tutorial  
on the rubyonrails.org website and have run into a little snag. I have  
my database setup and created my model and views... and I even got rake  
to work successfully, but whenever I try to hit the website  
(http://rails.benschumacher.com/friends/display), I'm getting this in  
my error log:

/usr/local/lib/ruby/site_ruby/1.8/rubygems/loadpath_manager.rb:5:in  
`require__': No such file to load -- digest/md5 (LoadError)
         from  
/usr/local/lib/ruby/site_ruby/1.8/rubygems/loadpath_manager.rb:5:in  
`require'
         from /usr/local/lib/ruby/1.8/pstore.rb:16
         from  
/usr/local/lib/ruby/site_ruby/1.8/rubygems/loadpath_manager.rb:5:in  
`require__'
         from  
/usr/local/lib/ruby/site_ruby/1.8/rubygems/loadpath_manager.rb:5:in  
`require'
         from /usr/local/lib/ruby/1.8/cgi/session/pstore.rb:13
         from  
/usr/local/lib/ruby/site_ruby/1.8/rubygems/loadpath_manager.rb:5:in  
`require__'
         from  
/usr/local/lib/ruby/site_ruby/1.8/rubygems/loadpath_manager.rb:5:in  
`require'
         from  
/usr/local/lib/ruby/gems/1.8/gems/actionpack-0.8.5/lib/ 
action_controller/cgi_ext/cgi_ext.rb:3
          ... 11 levels...
         from  
/usr/home/staff/ben/src/amazonmonitor/public/../config/environments/ 
production.rb:1:in `require'
         from  
/usr/home/staff/ben/src/amazonmonitor/public/../config/environments/ 
production.rb:1
         from  
/usr/home/staff/ben/src/amazonmonitor/public/dispatch.cgi:3:in  
`require'
         from /usr/home/staff/ben/src/amazonmonitor/public/dispatch.cgi:3

So it appears that it can't load my Digest::MD5 module, but just to  
test it myself, I tried it through irb:

$ irb
irb(main):001:0> require 'digest/md5'
=> true
irb(main):002:0> Digest::MD5.hexdigest('test')
=> "098f6bcd4621d373cade4e832627b4f6"
irb(main):003:0>

Anybody seen behavior like this before? I'm not currently running rails  
under FastCGI, just standard CGI, but I don't think this should make a  
difference. Any help would be appreciated.

Cheers,

Ben
