I have several GIT entries in the Gemfile.lock file and a list of gems
after the following lines, but this list looks much more extensive than
'gem list' shows ...

GEM
   remote: https://rubygems.org/
   specs:
     <list of gems>

Then under DEPENDENCIES, I see ...

rails (= 3.2.13)

Does that explain my rails version? I don't see any references to 4.0.0.

Yes, I've already found that and been reading, thanks.

I used rvm to install same ruby-1.9.3-p392 as the VPS, following a doc
here...

https://www.digitalocean.com/community/tutorials/how-to-install-rails-apache-and-mysql-on-ubuntu-with-passenger

After all setup in Apache, I am getting this Passenger application error
in the browser....

Perhaps I need to get some more gems installed? I did a 'gem install
bundle' and still get the error. My gem list is this so far on the dev
server I am trying to setup, not sure if this error is affecting things
as well...

root@media:/etc/apache2# gem list
/usr/share/ruby-rvm/rubies/ruby-1.9.3-p392/lib/ruby/1.9.1/yaml.rb:56:in
`<top (required)>':
It seems your ruby installation is missing psych (for YAML output).
To eliminate this warning, please install libyaml and reinstall your ruby.

On the production server, I have...

But again the list in the Gemfile.lock file lists many more. Just trying
to get a grasp of where to go from here, what is need to get this copy
to run, appreciate any help!
