ruby - How to avoid deprecation messages from RubyGems?

Question

After gem update --system, when I do something related to rubygems, I receive this message:

NOTE: Gem::Specification#default_executable= is deprecated with no replacement. It will be removed on or after 2011-10-01.

Gem::Specification#default_executable= called from /usr/lib/ruby/gems/1.8/specifications/rubygems-update-1.7.2.gemspec:11.

How can I avoid it? I've tried to remove rubygems and reinstall, but that didn't fix it.

You probably need to regenerate your gem specifications.

After installing RubyGems 1.8.1 you will see deprecations when loading your exsting gems. Run gem pristine --all --no-extensions to regenerate your gem specifications safely.
