Wincent Colaiuta: The standard update procedure yielded an error and didn’t actually install the new version

So the new dance is:

sudo gem install rubygems-update; sudo update_rubygems

Notable in this release:

Now uses ~/.gem/cache if the cache dir in GEM_HOME is not writable.

So if you forget to type sudo, what you asked for gets installed anyway, but just for you, leaving you with a mess to clean up.  No thanks.  Easily fixed:

find ~/.gem -type d | xargs chmod -w

Rubygems 1.3 also requires an upgrade to Rails.
