Polish your ruby gems

Rubygems was just released (by just i mean a week), for those of you who are no Ruby evangelist it won't ring a bell (Ruby equivalent of maven) for those who do its highly recommended to update.
On my system (Ubuntu with rubygems 1.1) the gem update --system approach didn't work so iv taken the second path and ran gem install rubygems-update followed by update_rubygems.
Now running gem --version yield the desired result (1.2).
