----
First off, I don't use Ubuntu ruby packages but use Enterprise Ruby
packages instead (on Lucid 10.04 LTS) so take my comments with a grain
of salt. The distributions just can't keep up with the fast moving
targets of ruby/rails/gems.

I wouldn't recommend running 'gem --update system' as that will get a
version of rubygems that probably is too new and will cause other
issues. I think you should probably get up to about version 1.4.2...

(run as root or add 'sudo'):
gem install rubygems -v="1.4.2"
update_rubygems

I think that you need to run 'update_rubygems' even if you stay at
version 1.3.7

As for jquery-rails - that would typically be brought in automatically
by an install of Rails 3 (ie... gem install rails -v="3.0.10") but one
would think that whoever created the Gemfile should have targeted a
specific version of rails near the top so it got installed immediately.
You may want to check with them which version of rails their site is
targeted to run or better yet, fix the Gemfile. (gem 'rails', ~>
'3.0.10')

Running ruby on rails sites on a shared host can be a challenge and it's
possible that RVM can help but to be honest, I have never used it (see
my reference above to using enterprise ruby).
