Aha! I know, I know! Case-insensitive Windows file system strikes again, 
and this time it bites RubyGems in the stern. Amusing :)

try require'redcloth' instead (note the lower case!), and see for yourself.

This is a RubyGems bug. To reproduce:

1. Take fresh Ruby install (must be on Windows)
2. Install RubyGems
3. Install RedCloth by gem install redcloth
4. Modify \ruby\lib\ruby\gems\1.8\gems\RedCloth3.0.3\redcloth.rb by 
adding puts 'HERE' in the beginning.
5. ruby -w -e "require 'RedCloth'"

C:\>ruby -w -e "require 'RedCloth'"
