Bundle Install will not update eventmachine gem

Question

I am trying to clone a repository from Github and I am on the step where I run "bundle install". However everytime I try to run this I get the following message:

An error occurred while installing eventmachine (1.0.3), and Bundler cannot
continue.
Make sure that `gem install eventmachine -v '1.0.3'` succeeds before bundling.

When I run "gem install eventmachine -v '1.0.3'" I get

Building native extensions.  This could take a while...
ERROR:  Error installing eventmachine:
    ERROR: Failed to build gem native extension.

I have tried a number of solutions (that have not worked) that I found online:

1. I've changed my ruby version to 2.1.5 in my .ruby-version file and gemfile.

2. I have also changed the eventmachine version in my gemfile.lock and gemfile to 1.0.4 and then also 1.0.7. After each change I then tried to run bundle install or gem install eventmachine. Which just produced the following:
