keep getting "undefined method `map' for nil:NilClass (NoMethodError) " in new server

hi guys,

I have a new development server (ubuntu 10). I have done the following (the versions match my existing development machine which works fine): 1. installed ruby 1.9.1p378 2. installed ruby gems 1.3.7 3. installed rails 2.3.8 (used "gem install rails -v 2.3.8") 4. manually installed my other gems including sphinx and thinking sphinx with "gem install ..." 5. ran "sudo apt-get install ruby-dev ruby ri rdoc irb libreadline- ruby libruby libopenssl-ruby sqlite3 libsqlite3-ruby libsqlite-dev libsqlite3-dev"

here's what "gem list --local" gives me:

root@ct9a-dev:~/projects/myApp# gem list --local
