I ran into this issue. The problem was that I was loading the map building javascript in the view before I was loading the core gmaps javascript.

You can solve this by add a yield after your javascripts, and using a content_for block to place your map building javascript after the others. Something like this:

<script src="//maps.google.com/maps/api/js?v=3.13&amp;sensor=false&amp;libraries=geometry" type="text/javascript"></script>
<script src='//google-maps-utility-library-v3.googlecode.com/svn/tags/markerclustererplus/2.0.14/src/markerclusterer_packed.js' type='text/javascript'></script>    
<%= javascript_include_tag "application", "data-turbolinks-track" => true %>  
<%= yield :javascripts %>

and then, wherever you're building your map,

<% content_for :javascripts do %>
<script type='text/javascript'>
    handler = Gmaps.build('Google');
    /* rest of maps building JS */
</script>
<% end %>
