Rails - Aug 2009 - rake gems:install doesn't install gems listed on environments/development.rb

That''s it. The command works for all gems listed on config/
environment.rb and even for environments/test.rb and environments/
production.rb (using: $ RAILS_ENV=<environment name> sudo rake
gems:install), but just ignores all gems listed on environments/
development.rb.

Is this a know bug?
