I updated ruby gems, but it's still on version 1.3.5. Below is copied from my terminal:

~$ ruby -S gem -v
1.3.5
~$ ruby -S gem update

How can I get Gems updated to version 1.5.2?

   If you want to update RubyGems, you need to provide the --system option:

     gem update --system

   "gem update" alone will only update your existing gems, not RubyGems.

   See "gem help update" for detailed documentation.

   This is also shown in the RubyGems README:

   To upgrade to the latest RubyGems, run:

     $ gem update --system # you might need to be an administrator or root

   See UPGRADING.rdoc for more details and alternative instructions.

   I didn't mention I am using Ubuntu 10.04. After reading about the competing dpkg and gem package systems, it seems that installing rubygems from source is the easiest solution.

   Update:
   The Gem install worked. Here is how I did it,

   $ gem -v
   1.3.5
   $ sudo apt-get purge rubygems
   $ cd /usr/local/src/
   $ sudo wget http://production.cf.rubygems.org/rubygems/rubygems-1.5.2.tgz
   $ sudo tar xzvf rubygems-1.5.2.tgz
   $ cd rubygems-1.5.2/
   $ sudo ruby setup.rb
   RubyGems 1.5.2 installed
   === 1.5.2 / 2011-02-10
   RubyGems installed the following executables:
   /usr/bin/gem1.8
   $ gem -v
   1.5.2
   $ sudo gem update --system
