Answer 1

NOTE: RubyGems 1.1 and 1.2 have problems upgrading when there is no rubygems-update installed. You will need to use the following instructions if you see Nothing to update. If you have an older version of RubyGems installed, then you can still do it in two steps:

$ gem install rubygems-update  # again, might need to be admin/root
$ update_rubygems              # ... here too
