Rails 3: Passenger can't find git gems || gem is not checkout Please run bundle install

ails 3.0.0, Passenger 2.2.15:

Create a new Rails project
Add

gem 'paperclip', :git => 'git://github.com/lmumar/paperclip.git', :branch => 'rails3'

to your Gemfile
Do

bundle install

Everything OK, starting with

rails/script server

& accessing also works
However, when accessing with Passenger, it says:

git://github.com/lmumar/paperclip.git (at rails3) is not checked out. Please run

bundle install

(Bundler::GitError)

I have tried

bundler pack

(doesn't help) and setting BUNDER_HOME to ~/.bundler (the Paperclip git gets installed there by

bundler install

) in the .htaccess and various places in config/*.rb, but this wasn't successful, too.

~/.bundler is owned by the same user as the Rails project (Passenger runs under this user), so it can't be a permission problem. sudo is installed and called by

bundle install

.

--------------------------------------------

Im used to have this problem, resolve using

bundle --deployment

Which will install the gems in vendor/bundle

or bundle install --path vendor/bundle

to install the gems locally, instead of into system gems.

or

Mare sure that

RAILS_ROOT/.bundle/config

(SetEnv etc. didn't work for me) contains:

---
BUNDLE_PATH: /home/xxxxx/.bundler

Note BUNDLE_PATH, not BUNDLER_PATH! There was also an DISABLED_SHARED_GEMS=1 entry, I removed it.

Then bundler recognises the correct path even when loaded from Passenger. Without Passenger, it always worked (and used /home/xxxxx/.bundler, as said in the question)
