Trouble installing barkeep

[Salvatore Benedetto]

Hi there,

I'm struggling installing barkeep on Ubuntu 14.10.

I'm managed to fix some problems myself although I know zero about ruby.

The problem I'm facing now is the following when I try to connect to barkeep through nginx

cat log/unicorn.log

~barkeep/barkeep_server.rb:142:in `<class:BarkeepServer>': uninitialized constant BarkeepServer::AUTHENTICATION_PROTOCOL (NameError)

        from ~/barkeep/barkeep_server.rb:47:in `<top (required)>'

Any hints?
