Hello all,  
I just installed ruby enterprise edition with rails. I down loaded  
the  
latest version of gems and ran

`dan@dev:~/initial_install/rubygems-1.3.5$ sudo ruby 
setup.rb`  
Which returned:

```auto
RubyGems 1.3.5 installed
./lib/rubygems/custom_require.rb:31:in `gem_original_require': no such 
file
to load -- rdoc/rdoc (LoadError)
        from ./lib/rubygems/custom_require.rb:31:in `require'
        from ./lib/rubygems/commands/setup_command.rb:352:in `run_rdoc'
        from ./lib/rubygems/commands/setup_command.rb:247:in 
`install_rdoc'
        from ./lib/rubygems/commands/setup_command.rb:120:in `execute'
        from ./lib/rubygems/command.rb:257:in `invoke'
        from ./lib/rubygems/command_manager.rb:132:in `process_args'
        from ./lib/rubygems/command_manager.rb:102:in `run'
        from ./lib/rubygems/gem_runner.rb:58:in `run'
        from setup.rb:35 [/CODE]

Then I tried to install the mysql gem and got the following out put:
[CODE]dan@dev:~/initial_install/rubygems-1.3.5$ gem install mysql
WARNING: Installing to ~/.gem since /usr/lib/ruby/gems/1.8 and
          /usr/bin aren't both writable.

/home/dan/.gem/ruby/1.8/gems/mysql-2.8.1
for inspection.
