builder-2.1.2 and Errno::EINVAL errors

This is not a Windows issue.

While installing Rails 3 RC on Ubuntu, Ruby 1.8.7 I encountered the same problem.

However if you look at the error:

ERROR:  While generating documentation for builder-2.1.2
... MESSAGE:   Unhandled special: Special: type=17, text="<!-- HI -->"
... RDOC args: --ri --op C:/Ruby187/lib/ruby/gems/1.8/doc/builder-2.1.2/ri --tit
le Builder -- Easy XML Building --main README --line-numbers --quiet lib CHANGES
 Rakefile README doc/releases/builder-1.2.4.rdoc doc/releases/builder-2.0.0.rdoc
 doc/releases/builder-2.1.1.rdoc --title builder-2.1.2 Documentation

You will notice that this is not a Rails issue but a Builder issue. The RDoc documentation couldn't be generated for the Builder gem. It's not a show stopper as I can confirm that Rails 3 RC works fine even with that error.

To show that it's a Builder issue, this what you get while installing only builder:

Closing ticket.
