Ubuntu Database Error

I`m trying to get WarVOX working but when I get to the command: 'make database' I get an error:

nick@NICKUBUNTU:~/warvox$ make database Checking the database.. RAILS_ENV=production bundle exec rake db:migrate /home/nick/.rbenv/versions/2.2.1/lib/ruby/gems/2.2.0/gems/rex-2.0.5/lib/rex/proto/http/server.rb:83: warning: duplicated key at line 84 ignored: "jpeg" /home/nick/.rbenv/versions/2.2.1/lib/ruby/gems/2.2.0/gems/rex-2.0.5/lib/rex/proto/smb/exceptions.rb:11: warning: duplicated key at line 12 ignored: 0 /home/nick/.rbenv/versions/2.2.1/lib/ruby/gems/2.2.0/gems/rex-2.0.5/lib/rex/proto/smb/exceptions.rb:17: warning: duplicated key at line 18 ignored: 128 == 20121228171549 InitialSchema: migrating ==================================== -- execute("CREATE EXTENSION IF NOT EXISTS intarray") rake aborted!
