I answered these questions.
Thanks for the hint - where would I find that installer?
What I worried about is that with the different installation I will not be able to follow the tutorials in the book.
And if the book does not help me getting up to speed - what's the point in buying the book, right?
I added these phrases because I'm not 100% sure it works. If you prefer I can say "it works", but that isn't true. Installing Rails without using InstantRails doesn't defeat the purpose of reading the book. It think it doesn't only teach how to install?
The book suggests using the InstantRails installation and that is what we are doing. What we wish to know is why we receive the WEBrick error using that installation - not a workaround using some alternative installation method; That defeats the purpose of following the book. Personally, phrases like "almost as easy" and "probably works" don't do much to instill any confidence in the proposed solution either.
