errors compiling website in minimal ruby installation

[drivers2000]

I tried to follow instructions in the README.md to test changes to the website but received errors from missing packages. I'll attach the full log as a file, but here is a shorter version of what I did.

$ docker run -it --rm -v .:/src -p 3000:3000 ruby bash
root@7313a2a80974:/# gem install nanoc kramdown adsf
Fetching pastel-0.8.0.gem
...
32 gems installed

Then I changed the folder containing my working copy of the repository and tried to build:

root@7313a2a80974:/# cd /src
root@7313a2a80974:/src# ls
README.md  Rakefile  Rules  content  crash.log	deploy.sh  layouts  lib  nanoc.yaml  output  tmp
root@7313a2a80974:/src# nanoc
Loading site… done
Compiling site…
update  [1.37s]  output/clients/index.html
...
update  [0.44s]  output/news/2011/index.html

Error: cannot load such file -- builder

Install the 'builder' gem using `gem install builder`.

I followed that instruction and was able to build the site. However, when I tried to run the site I got another error about a missing package.

Captain! We’ve been hit!
LoadError: Couldn't find handler for: puma, falcon, webrick.
/usr/local/bundle/gems/rackup-2.2.1/lib/rackup/handler.rb:81:in 'Rackup::Handler.pick': Couldn't find handler for: puma, falcon, webrick. (LoadError)
	from /usr/local/bundle/gems/rackup-2.2.1/lib/rackup/handler.rb:91:in 'Rackup::Handler.default'
...

I arbitrarily chose puma and then was able to run the site:

root@7313a2a80974:/src# gem install puma
...

root@7313a2a80974:/src# nanoc view
...
* Listening on http://127.0.0.1:3000
Use Ctrl-C to stop

Because of the port forwarding in my original docker command I was able to connect to the site on localhost:3000.

I found that I could fix the problem by adding two extra packages to the initial command in the README. I'll create a pull request with this change.
