Rails 3.0.0, Passenger 2.2.15:
gem \'paperclip\', :git => \'git://github.com/lmumar/paperclip.git\', :branch =
Solution (took me a few hours):
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)
