That means that you remove the cache gem folder? The gem list is only
going to display the installed ones.

Can you enter the following URL in your browser, download it to a
location and then try installing it?

http://gemcutter.org/gems/rubygems-update-1.3.5.gem

The downloaded file should weight 279K.

then, from the command line where you downloaded that file:

gem install rubygems-update-1.3.5.gem

If doesn't work, then you're behind a firewall or proxy that is
blocking all the Amazon S3 downloads and is downloading garbage that
RubyGems cannot install
