I thought uninstalling rails 2.3.8 would uninstall that version then a
different version would be "current". I paused at that question. I have
to admit.
BTW...
gem list --local

Looks like several versions of rails are still hanging around!
But...
sudo gem uninstall rails
ERROR: While executing gem ... (Gem::InstallError)
cannot uninstall, check `gem list -d rails`
And...
gem list -d rails
*** LOCAL GEMS ***
rails (2.3.5, 2.2.2, 1.2.6)
Author: David Heinemeier Hansson
Rubyforge: http://rubyforge.org/projects/rails
Homepage: http://www.rubyonrails.org
Installed at (2.3.5):
/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/gems/1.8
(2.2.2):
/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/gems/1.8
(1.2.6):
/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/gems/1.8
Web-application framework with template engine, control-flow layer,
and ORM.
FYI
So it looks like heading over to
/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/gems/1.8
and deleting gems/* may do it. In this directory there is an alias to
/Library/Ruby/Site and one to /Library/Ruby/Gems, which has some
interesting content.
So, Mr Schroeder, given this:
gem env
RubyGems Environment:
- RUBYGEMS VERSION: 1.3.5
- RUBY VERSION: 1.8.7 (2009-06-12 patchlevel 174)

What do I drag to the trash? Looks like the stuff in the three GEM
PATHS?
