How do I fix Rubygems recent deprecation warning?

Question

I have recently run updates:

gem update --system
gem update

Now, I come with a lot of deprecation warnings each time I load a gem. For example, rails console:

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 /Users/user/.rvm/gems/ruby-1.9.2-p180@global/specifications/rake-0.8.7.gemspec:10.
NOTE: Gem::Specification#default_executable= is deprecated with no replacement. It will be removed on or after 2011-10-01.

I use RVM, Ruby 1.9.2 and Rubygems 1.8.1. Any way to get around this problem? Revert to an older version of rubygems?

I had to downgrade to 1.6.2. Those notices are absolutely ridiculous. They make the latest version completely unusable. There should really be a way to disable them, but until then:

sudo gem update --system 1.6.2
