Just wanted to post my notes on how I was able to install Ruby and Gem  
on Ubuntu Gutsy:

$ sudo apt-get install ruby ruby1.8-examples rdoc ri libruby-extras  
rubygems

$ ruby -v  
ruby 1.8.6 (2007-06-07 patchlevel 36) [i486-linux]

$ gem -v  
/usr/bin/gem:23: uninitialized constant Gem::GemRunner (NameError)

$ sudo ruby -i.bak   
-lne ‘print “require \047rubygems/gem\_runner\047”   
if /^require /; print’ /usr/bin/gem

$ gem -v  
1.0.1

$ sudo gem update --system

Thanks to these two posts:
