veewee installation failed : gem eventmachine can't compile with Ruby 2.2.0

Hi ! I tried to use your project today. I followed the procedure with RVM. The command bundle install fails because of a an incompatibility with the version you require to use ruby 2.2.0, but you also require to install eventmachine 1.0.0.beta.3, which can't be compiled under this version of Ruby.

ruby-2.2.0 - #gemset created /usr/local/rvm/gems/ruby-2.2.0@veewee

Don't run Bundler as root. Bundler can ask for sudo if it is needed, and
installing your bundle as root will break this application for all non-root

An error occurred while installing eventmachine (1.0.0.beta.3), and Bundler
cannot continue.
Make sure that `gem install eventmachine -v '1.0.0.beta.3'` succeeds before
bundling.

This problem is already known here : https://github.com/eventmachine/eventmachine/issues/509

I created a Dockerfile to quicly reproduce the issue if you want :

FROM partlab/ubuntu

# install RVM
RUN gpg --keyserver hkp://keys.gnupg.net --recv-keys 409B6B1796C275462A1703113804BB82D39DC0E3 && \
    \curl -sSL https://get.rvm.io | bash -s stable && \
    echo "source /etc/profile.d/rvm.sh" > /root/.bashrc && \
    gpasswd -a root rvm

# install veewee
RUN bash -ci 'rvm install ruby'
RUN git clone https://github.com/jedi4ever/veewee.git /root/veewee
WORKDIR /root/veewee
RUN bash -ci 'rvm use ruby@veewee --create && \
    gem install bundler && \
    bundle install'

Can you fix it please ?

Thanks !
