It says unicorn not found but it is. I have it in my Gemfile and I also installed it with 'gem install unicorn'.

Have you installed it for the correct user? Or locally to your current?

User in unicorn.rb is ben.  When I am logged in as ben I can type unicorn and it finds/runs it.  Ime using rbenv.  I did have this working and reinstlled rbenv localy in the user.  sould of mentioned ths buy it was a 2PAM post just before I caled it a day.  Will post config files later when I get home.

I'm not a user of rbenv, but when I still used ruby and RVM I had to load rvm manually in startup scripts. RVM even had a function to create shims which did this for you.

This is necessary, because RVM (and probably RBenv) are only loaded in a log in shell through its bash/zsh/whatever-rc files. The various init-systems do not use login-shells but start their stuff in very minimal environments, therefore you have to do lot of the setup on your own.
