Gems for some reason on Debian/Ubuntu seems to want to install in 
/usr/lib/ruby instead of /usr/local (rather annoying) I'd take a look 
and see if that is what it did?

On Dapper running ruby from the repository and Gems from source I 
install gems to /usr/local/lib/site_ruby this way...

export GEM_HOME=/usr/local/lib/site_ruby/1.8/gems
ruby setup.rb config --prefix=/usr/local/ 
--site-ruby/usr/local/lib/site-ruby
ruby setup.rb setup
ruby setup.rb install

Set necessary environment vars in /etc/environment

Add /usr/local/lib/site-ruby/1.8/gem/bin to the PATH entry
Add GEM_HOME="/usr/local/lib/site_ruby/1.8/gems"

Restart so they take system wide effect


I typed that (quickly) from memory away from my ubuntu box so you may 
want to check/alter the directories a bit...
