Debian wont add the gems executables on the path. The file should be on /var/lib/gems/1.8/bin/ or within the gem directory itself /var/lib/gems/1.8/gems/rails-x.x.x/bin. You should add the directory to your path or create a symlink to somewhere on your path.
Hope it helps. Cheers.
These ruby scripts differs from each other: /var/lib/gems/1.8/bin/rails /var/lib/gems/1.8/gems/rails-2.3.4/bin/rails
Don't know why 
The first one gives me an error asking to install a gem. I installed fcgi, mongrel and i am still installing. I'm wondering why these were not installed by gem when I executed 'gem install rails'.
The second one reports me the attached error image.
