Message:
Just to update:

I suck.  Just trying to upgrade to rubygems 1.8.1 with a clean install of 
1.9.3dev 
will break.  No need to install anything else.

Message:
I did this on a fresh install of 1.9.3dev:


  504  ruby -v
  505  cd ~/Downloads/
  506  ls -tr
  507  tar zxvf rubygems-1.6.1.tgz 
  508  cd rubygems-1.6.1
  509  ls
  510  ruby setup.rb 
  511  gem -v
  512  gem update --system
  513  history | tail

Aaron... I can't repro at all.

Message:
Aaron, do you think this is caused by the same root cause I suspect in 
[#29190], namely mismatched rubygems.rb wrt require 'rubygems/deprecate'

Message:
While I'm not seeing the same error, I too can't upgrade from 1.6.2 or 1.7.2 to 
1.8.0/1.  I've tried 3 times now:
1. MRI 1.9.2, rubygems 1.7.2.
** Did `gem update --system` then `gem pristine --all --no-extensions`
2. MRI 1.9.2, rubygems 1.6.2
** Did `gem update --system` then `gem pristine --all --no-extensions`
3. MRI 1.9.2, rubygems 1.6.2
** Did `gem install rubygems-update && update_rubygems`

By doing the 1st 2, I can no longer use any `gem` commands; even just `gem` 
results in a backtrace (see more 
[here]{http://stackoverflow.com/questions/5932984/how-do-i-get-gem-working-again-after-upgrading-to-rubygems-1-8-x}

With the 3rd command, the upgrade just fails (with the same backtrace as the 
first 2) but I'm left with a usable install, just still on rubygems 1.6.2.

Here's the backtrace:
