Would it have anything to do with this?

  hook /usr/lib/ruby/gems/1.8/gems/rubygems-update-0.9.2/./post-
install.rb failed:
  undefined method `post_install_message' for #<Gem::Specification:
0xb7ae957c>
  Try 'ruby setup.rb --help' for detailed usage.

I take it the current cure is to delete the source_cache?
