Odd, RubyGems isn't finding some of its own libraries.  If the files 
were missing, I would have expected an error on the require.  Instead it 
looks as if the files are found, but the contents are not there. 
Interesting.

Try the following commands in irb:

   require 'rubygems/remote_installer' # makes sure the file can be 
found
   Gem::RemoteInstaller                # makes sure the class was loaded
   $:.find { |d| File.exist? File.join(d, 
'rubygems/remote_installer.rb') }
                                       # Finds the location of the 
require file

The last command should show the location of the file containing the 
RemoteInstaller class.  Open the file and make sure it contains a proper 
definition for RemoteInstaller.
