Q: 

Problem including installed gems

I'm having issues requiring gems in my rails application, I have tried multiple gems, and I made sure they were installed by issuing "gem list --local", they're there .. they just can't be found, I keep getting this error "Could not find RubyGem twitter4r (= 0.2.0)" for twitter4r gem and a similar one for other ones.

I feel that I should mention that I had jRails installed and it used to give a warning about something being deprecated in its rake file when I issue "gem env".

I'm running on Snow Leopard 10.6, ruby 1.8.7, and rails 2.3.8.

Please help!
