Foreman » Smart Proxy

When trying to upgrade from 1.13 to 1.14 smart proxy on Windows 2008R2, I receive the following error when trying to run the proxy:

C:\smart-proxy>bundle exec ruby C:\smart-proxy\bin\smart-proxy
C:/smart-proxy/lib/proxy/log.rb:35:in `<class:LoggerFactory>': uninitialized con
stant Proxy::LoggerFactory::Syslog (NameError)
from C:/smart-proxy/lib/proxy/log.rb:22:in `<module:Proxy>'
from C:/smart-proxy/lib/proxy/log.rb:15:in `<top (required)>'
from C:/smart-proxy/lib/launcher.rb:1:in `require'
from C:/smart-proxy/lib/launcher.rb:1:in `<top (required)>'

from C:/smart-proxy/bin/smart-proxy:5:in `require'
from C:/smart-proxy/bin/smart-proxy:5:in `<main>'

I've tried Ruby 2.3.3. and ruby 2.2.6 and both have this issue. Smart proxy version 1.13 works fine on this machine.
