Updating to RubyGems 1.3.0 on Mac OS X Leopard 10.5.4

When attempting to stall final release of Merb 1.0, I got an error message that I needed RubyGems version >=1.3.0:

ERROR: Error installing merb:
merb-core requires RubyGems version >= 1.3.

So I did the usual "gem update --system" but got an error:

$ sudo gem update --system
Updating RubyGems
Updating rubygems-update
Successfully installed rubygems-update-1.3.0
ERROR: While executing gem ... (NameError)
undefined local variable or method `remote_gemspecs' for #
$ gem --version

I found that you have to run a second set of instructions:

$ sudo gem install rubygems-update
Successfully installed rubygems-update-1.3.0
1 gem installed
$ sudo update_rubygems
Installing RubyGems 1.3.0
