Problem with outdated RubyGems

Error :
Rails requires RubyGems >= 1.3.1 (you have 1.2.0). Please `gem update –system` and try again .
Fix :
As it is clear from the error message, updating the RubyGems will resolve this issue.
Reinstall the ruby gems using the following commands:
gem install rubygems-update
update_rubygems

Error : Gem::SourceIndex#search

Error :
boot.rb:20:Warning: Gem::SourceIndex#search support for String
patterns is deprecated

Fix :
There is a call to Gem Source Index in  boot.rb:
‘Gem.cache.search’
Just replace ’search’ with ‘find_name’ .
It should look something like this :
rails_gem = Gem.cache.find_name(`rails’,”=#{rails_gem_version}.0″).sort_by { |g| g.version.version}.last

Error while installing RubyGems

Error :

/usr/local/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:31:in `gem_original_require’: no such file to load — zlib (LoadError)
Fix :
Ruby-zlib should be built into Ruby 1.8
Build ruby-zlib manually.
wget http://www.blue.sky.or.jp/atelier/ruby/ruby-zlib-0.6.0.tar.gz
tar xvzf ruby-zlib-0.6.0.tar.gz
cd ruby-zlib-0.6.0
ruby extconf.rb
make
make install
Now, reinstall Ruby Gems from source.
