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....

cannot load such file -- bundler/setup (LoadError)

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.

*** LOCAL GEMS ***

bundle (0.0.1)
bundler (1.7.4)
daemon_controller (1.2.0)
passenger (4.0.53)
rack (1.5.2)
rake (10.3.2)

On the production server, I have...

*** LOCAL GEMS ***

activemodel (4.0.0)
activerecord (4.0.0)
activerecord-deprecated_finders (1.0.3)
activerecord-mysql-adapter (0.0.1)
activesupport (4.0.0)
arel (4.0.0)
atomic (1.1.13)
bigdecimal (1.1.0)
builder (3.1.4)
bundler (1.3.5)
i18n (0.6.5)
io-console (0.3)
json (1.5.5)
minitest (4.7.5, 2.5.1)
multi_json (1.7.9)
mysql (2.9.1)
rake (0.9.2.2)
rdoc (3.9.5)
thread_safe (0.1.2)
tzinfo (0.3.37)

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!
