no such file to load -- md5 (LoadError)

[Ken Keller]

require 'bcrypt'; BCrypt::Engine.generate_salt
and
rake textcaptcha:config
both cause
no such file to load -- md5

Using ruby 1.9.2p0 & rails 3.1 on Win7.

[Matthew Hutchinson]

This must be a gem related issue with your machine/environment. I've tested the gem with Rails 3.1 and Ruby 1.9.2 and had no issues.
