In a fresh ruby install you usually have no installed gems.

First you might update the gem utility itself to the latest:
 
 > gem update --system

Then install the gems you need with 'gem install <gem-name>'

You can get a list of what gems are available for install with:
> gem list --remote rails

I think your gem program points to gem1.9, and therefore output is empty. If you do "gem1.8 list" you will get all the gems installed with rubu1.8.

Also if "ruby -v" outputs ruby 1.9, and you still want to use ruby1.8 then perhaps you need to symlink ruby1.8 to ruby.

First of all, I hope you are linux/mac. If yes, google "symlink" or "ln -s howto". In short, what you need is this:

>ln -s file_you_want_to_symlink  new_path

or in your case most probably, it will be

> sudo ln -s /usr/bin/ruby1.8 /usr/bin/ruby
