This is not the best route unfortunately. You really do want to use rubygems to manage the gems. This link seems to show a reasonable route http://excid3.com/blog/2010/10/ruby-on-rails-3-and-mysql-on-ubuntu-10-10/ Once you manage to get something working, before starting any serious work, I would also highly recommend using rvm. It can be a little fiddly to get working but is worth the effort. One final point, Rails 3 with ruby 1.9.2 (on Ubuntu at least) seems to have startup speed issues. At the moment it may be best to stick to ruby 1.8.7 (which you may well already have installed via apt, which is ok). Rails 3 is fine with 1.8.7.
