Error During Rails Installation

Question

I am trying to find out if this error during my rails installation matters at all

Installing RDoc documentation for builder-3.0.4...

Answer 1

I think it will only affect usage of the help documentation (that is what RDoc is for) so wouldn't actually affect rails itself.

I've seen a few doc issues lately. For some of them gem install rdoc to upgrade to the latest version of the RDoc package itself has helped.

Almost certainly not since this just occurred in the generation of the documentation for Builder (as opposed to something that could affect your code at runtime). But here is an explanation of the issue for your version.
