Errors with 'require' in Ruby - Ubuntu 10.04

I encountered some errors when running my code, just out of the blue; so i googled but didn't manage to find answers for the problem.

./curb.rb:17:in `gets': No such file or directory - 6fd9c1c6b63137c7d93139472696b2e3 (Errno::ENOENT)
from ./curb.rb:17
from /usr/local/lib/site_ruby/1.8/rubygems/custom_require.rb:29:in `gem_original_require'
from /usr/local/lib/site_ruby/1.8/rubygems/custom_require.rb:29:in `require'
from main.rb:18

I had a hunch though, that it might have something to do with my gem, that i tried my luck updating it using the command;

$ sudo gem update -- system

And here is the list of newly updated gems;

$ gem list
