I'm no big expert, but at least we have similar systems so a comparison
might be useful in tracking this stuff down. I am using,

ruby 1.8.6 (2008-03-03 patchlevel 114) [powerpc-darwin8.9.0]

My working ruby is in /usr/local.

I've left the built-in ruby in place, so I also have /usr/bin/ruby:

ruby 1.8.2 (2004-12-25) [powerpc-darwin8.0]

But I don't use it. 

But I don't think that's the issue. When you get an error message
warning that there is no directory rubygems-update-1.3.1, I tend to
think that this is because you are supposed to have such a directory.
Your quoted material says "Successfully installed
rubygems-update-1.0.0"; but the current version is 1.3.1. So that must
be what rubygems is looking for. I *do* have such a directory:

/usr/local/lib/ruby/gems/1.8/gems/rubygems-update-1.3.1

I think you need that before you can proceed. Of course mine is in a
different place because my ruby is in a different place.

So you could probably get things working by following this procedure
(but use sudo):

$ gem install rubygems-update
$ update_rubygems

However, you don't really need to do that, because, as the Google-found
ruby-forge page I cited says, there was a bug, it has been fixed, and
you can check out working code from the trunk. So your setup.rb approach
should also now work.
