This may be due to a bug from our upgrade to Ruby 2, RubyGems 2, and RDoc 4. That said, the SHA the the docs refer to doesn't seem to exist (anymore?) in will_paginate, so there are a number of reasons the build failed, one of which was there was some odd syntax (or edge case) in the Ruby code that caused YARD to go into an inconsistent state. These are rare but there are some known coding styles that YARD is incompatible with and can cause weird results. I would look into this, but I can't track down a reproduction scenario here, so I would suggest a pull request if you know what the root cause was. It's also important to note that YARD is not perfect, and bugs happen, so reporting those on http://github.com/lsegal/yard is more than appreciated-- submitting a patch is even better.
Let me know if you have other issues.

Got it- I have never looked into documentation generation like this, thanks
for the tip!
