要約すると以下のことでおこになってる

No timezone data source could be found. To resolve this, either install TZInfo::Data
(e.g. by running `gem install tzinfo-data`)

ようするに tzinfo-data がないということ。で、Gemfileを見ると、実は書いてある。

source 'https://rubygems.org'
  : 
  : 
# Windows does not include zoneinfo files, so bundle the tzinfo-data gem
gem 'tzinfo-data', platforms: [:mingw, :mswin]

なのにインストールされてないというのだ

解決方法

64bit版のRubyはplatformsが x64_mingw になるので、これを追加してやれば良い。つまりこうする

source 'https://rubygems.org'
  : 
  : 
# Windows does not include zoneinfo files, so bundle the tzinfo-data gem
gem 'tzinfo-data', platforms: [:mingw, :mswin, :x64_mingw]

これを書いたあと、おもむろに bundle update すると tzinfo-dataがインストールされる。そして、rails serverも無事に動く。

ちなみに、masterではもう修正されている（4.1.1になったら直るのかな）。
