Here's my solution:

[68] erikh@islay ~% ruby quiz.rb date
/usr/lib/ruby/1.8/date.rb
[69] erikh@islay ~% ruby quiz.rb date digest/sha1
/usr/lib/ruby/1.8/date.rb
/usr/lib/ruby/1.8/x86_64-linux/digest/sha1.so
[70] erikh@islay ~% irb -r quiz.rb
irb(main):001:0> require 'digest/sha1'
/usr/lib/ruby/1.8/x86_64-linux/digest/sha1.so
=> true
irb(main):002:0> require 'date'
/usr/lib/ruby/1.8/date.rb
/usr/lib/ruby/1.8/rational.rb
/usr/lib/ruby/1.8/date/format.rb
/usr/lib/ruby/1.8/rational.rb
=> true

Code emailed to Matthew. Again, thanks for the fun. :)
