Haml rendering error on production

I'm writing a Rails 3 application on Mac OSX and it runs fine under both development and production. When I deploy the app with Passenger I get a error in one of my views. This is how the view looks like:

%p#refresh= link_to 'Refresh', '#', id: "refreshAreaLink"

#newAreaParagraph
  = link_to 'New area', '#', id: "createNewAreaLink"

- for area_group in AreaGroup.all
  .areaGroup
    = area_group.name
  %ul
  - for area in Area.find_all_by_area_group_id(area_group.id)
    %li.areaList
      = link_to area.name, area, :remote => true, :class => "areaLink", :id => "prufa"
.areaGroup
  No group
- for area in Area.find_all_by_area_group_id(nil)
  %li.areaList
    = link_to area.name, area, :remote => true, :class => "areaLink", :id => "prufa"

And this is the error I'm getting:

Is there something obvious I'm doing wrong?

It looks like line #4 is using the new Ruby 1.9 hash syntax of key: value instead of :key => value. Is your production environment running Ruby 1.8? If so, you'll either need to upgrade to 1.9, or use the Ruby 1.8 compatible format:

  = link_to 'New area', '#', :id => "createNewAreaLink"
