Important! The old install method should not be necessary.

A better fix is to run:
$ gem pristine --all --no-extensions

Then run this:
$ gem pristine --all

You may need to run those commands several times.

If you still have problems you can then force the old install method with:
$ chicken_little force_install}
  end
