On my ubuntu 8.04, I did a
gem update --system
and now everytime i try to run the gem command line from console, i get the error:
/usr/bin/gem:10: undefined method `manage_gems' for Gem:Module (NoMethodError)
What's going on? My version of rubygem was very old, but at least it was working before. How do I fix the above problem or roll back to my earlier version?
