Install RubyGems Legacy Versions

To install a legacy version of RubyGems, you will need some version installed first, so use aptitude, yum, zypper etc:

apt-get install rubygems

Then revert to an older version (for example 1.3.6):

gem install rubygems-update -v=1.3.6
update_rubygems

Check your version with

gem env
