Could somebody post simple steps for installing a plugin from source on
1.6.1?
The plugin is https://github.com/jcmcken/foreman_custom_banner
When I get to the step:
echo 'gem ''foreman_custom_banner''' >
~foreman/bundler.d/foreman_custom_banner.rb
followed by restart it fails with:
Undefined local variable or method `foreman_custom_banner' for Gemfile
from (eval):1 (Bundler::GemfileError)
I've tried following the "from source" installations on the old wiki page Version 14 - History - How to Install a Plugin - How to Install a Plugin - Foreman
as well as the manual http://www.theforeman.org/manuals/1.6/index.html#6.1InstallaPlugin
I'm sure it's some newbie error since I don't know Rails/Rake/Ruby/Gems/whatever 
Thanks in advance!
