rubygems refuses to install dependencies

[Gaius]

For any gem with dependencies I have the following problem:

# attempt 1:
sudo gem install mojombo-jekyll
ERROR: Error installing mojombo-jekyll:
mojombo-jekyll requires RedCloth (= 4.1.0, runtime)

# attempt 2:
sudo gem install mojombo-jekyll --include-dependencies
INFO: `gem install -y` is now default and will be removed
INFO: use --ignore-dependencies to install only the gems you list
ERROR: Error installing mojombo-jekyll:
mojombo-jekyll requires RedCloth (= 4.1.0, runtime)

# attempt 3:
sudo gem install mojombo-jekyll -y
INFO: `gem install -y` is now default and will be removed
INFO: use --ignore-dependencies to install only the gems you list
ERROR: Error installing mojombo-jekyll:
mojombo-jekyll requires RedCloth (= 4.1.0, runtime)


How can I convince rubygems that I _really_ want to include
dependencies?

Hi,
Are you installung this gem from local gem file, because when I
did the same command I got...


sudo gem install mojombo-jekyll
[sudo] password for jack:
ERROR: could not find gem mojombo-jekyll locally or in a repository


Try

sudo gem install mojombo-jekyll -s http://gems.github.com/
