I'm trying to follow the instructions for downgrading rubygems from this env:

$ gem env
RubyGems Environment:
- RUBYGEMS VERSION: 1.8.5
- RUBY VERSION: 1.9.2 (2010-08-18 patchlevel 0) [x86_64-linux]
- INSTALLATION DIRECTORY: /usr/local/lib/ruby/gems/1.9.1
- RUBY EXECUTABLE: /usr/local/bin/ruby
- EXECUTABLE DIRECTORY: /usr/local/bin
- RUBYGEMS PLATFORMS:
- ruby
- x86_64-linux
- GEM PATHS:
 - /usr/local/lib/ruby/gems/1.9.1
 - /home/ops/.gem/ruby/1.9.1
- GEM CONFIGURATION:
 - :update_sources => true
 - :verbose => true
 - :benchmark => false
 - :backtrace => false
 - :bulk_threshold => 1000
 - "gem" => "--no-rdoc --no-ri"
- REMOTE SOURCES:
 - http://rubygems.org/

back to 1.3.7 to assist in debugging some probably unrelated issues. But it fails with this error:

$ sudo gem update --system 1.3.7

   Hello,

   While RubyGems 1.3.7 works on Ruby 1.9.x, it can't be installed using these methods.

   I recommend you downgrade instead to 1.7.2 or 1.6.2 which is known they successfully install on Ruby 1.9.x

   Please let us know if that solve your issues.

   OK, thanks.

   It would be helpful if this limitation was more clearly spelled out on the page that talks about upgrading and downgrading. I was using the example almost exactly as given, so it was surprising that it didn't work.

   The thing is that it worked for me under RVM:

   And also updating the system version of Ruby that came with Snow Leopard:

   So perhaps there is something else interfering there?

   Hello,

   Sorry I tested against 1.8.7, not 1.9.x

   With 1.9.2 I can reproduce the issue you mention:

   https://gist.github.com/1006834

   And I've created the proper bug report for RubyGems:

   Thank you for your report.

   Sounds like this is resolved, closing it out!
