puppet doc questions

[llo...@oreillyauto.com]

Does puppet doc require a specific version of any gems (such as rdoc or rake) to operate?

I'm getting some errors when I try to generate my rdoc now.

# puppet doc --output /var/www/test --modulepath /etc/puppet/environments/test/modules -m rdoc
RDoc::RDocError is deprecated and will be removed in RDoc 4
Could not generate documentation: uninitialized constant RDoc::RDoc::Generator


I am on puppet 2.7.17, Ubuntu 12.04 (32bit, server).

As an update, I did find http://projects.puppetlabs.com/issues/11786 which indicates that rdoc 1.x is needed, and that rdoc 2.x and 3.x will not work.

However, the oldest gem available is 2.0...

Any recommendations?
