Error installing RedCloth on Rails 3.0.3 and RVM on Ubuntu 10.10

Question

I'm trying to add Redcloth to my Gem file, and when I run 'bundle install', I get the following:

Installing RedCloth (4.2.6) with native extensions /home/user/.rvm/rubies/ruby-1.9.2-p136/lib/ruby/site_ruby/1.9.1/rubygems/installer.rb:529:in `rescue in block in build_extensions': ERROR: Failed to build gem native extension. (Gem::Installer::ExtensionBuildError)

    from /home/user/.rvm/gems/ruby-1.9.2-p136@vendorguide/bin/bundle:19:in `'

If I run "gem install RedCloth" and then run "bundle install", it works, however when I actually try to use RedCloth in a model 'Vendor.rb' I get:

Uninitialized constant Vendor::RedCloth

Here's my gemfile:

gem 'rails', '3.0.3'


gem "compass", ">= 0.10.6"

gem "haml"
gem 'formtastic'

gem 'devise', :git => 'git://github.com/plataformatec/devise.git',  :branch => 'master'
gem 'oa-oauth', :require => "omniauth/oauth"
gem 'mogli'
gem 'dalli'
gem 'exceptional'
gem 'json'
gem 'RedCloth'

group :test, :development do
  gem "ruby-debug19"
  gem "rspec-rails", "~> 2.4"
  gem 'sqlite3-ruby', :require => 'sqlite3'
  gem 'hpricot'
  gem 'ruby_parser'
  gem 'heroku'
  gem "flutie"
end

group :test do
  gem 'cucumber-rails'
  gem 'capybara'
  gem 'database_cleaner'
  gem 'mocha'
  gem 'factory_girl_rails'
  gem 'shoulda'
  gem 'ZenTest'
  gem 'fakeweb'
end

And here's my model:

class Vendor  ActiveRecord::Base
  has_many :reviews
  belongs_to :user

  validates_presence_of :name
  validates_presence_of :description

  before_save :convert_text

  def convert_text
    self.description = RedCloth.new(self.description).to_html unless self.description.nil?
    self.services_description = RedCloth.new(self.services_description).to_html unless self.services_description.nil?
    self.clients_description = RedCloth.new(self.clients_description).to_html unless self.clients_description.nil?
    self.pricing_description = RedCloth.new(self.pricing_description).to_html unless self.pricing_description.nil?
    self.press = RedCloth.new(self.press).to_html unless self.press.nil?
  end
end

Thanks in advance.

This might be related to the problem I had this morning with RedCloth.

I also installed version 4.2.6 of RedCloth, and then could not use it in a Sinatra app, no matter what I did. (I got a lot of similar errors, Uninitialized constant RedCloth.) However, the RedCloth site (http://redcloth.org/) says the latest stable version is only 4.2.2.

I uninstalled 4.2.6 and installed 4.2.2, and it worked perfectly.

Try adding the restriction to your Gemfile, i.e. gem 'RedCloth', '4.2.2'
