This should help:

Based on some scattered info on irc, you may need to run `gem` with:

    `ruby --disable-gems -S gem`

Possibly `update_rubygems` too... But I've tried neither yet, so let me know what you see (whether you have problems downgrading or not)...

Worst case scenario, you can get the rubygems tarball of choice and run setup.rb to install it.
