I can’t get ruby gems to install.  
Every time I run setup.rb (with sudo) I get this message

Desktop/rubygems-0.9.4/setup.rb:134:in `initialize': Is a directory - .config (Errno::EISDIR) from Desktop/rubygems-0.9.4/setup.rb:134:in `open’  
from Desktop/rubygems-0.9.4/setup.rb:134:in `save' from Desktop/rubygems-0.9.4/setup.rb:992:in `exec\_config’  
from Desktop/rubygems-0.9.4/setup.rb:812:in `invoke' from Desktop/rubygems-0.9.4/setup.rb:773:in `invoke’  
from Desktop/rubygems-0.9.4/setup.rb:1578

Is this an issue with ubuntu? I’m running the latest version (7.10  
gutsy)

instead of using setup.rb i would just do the following since u have  
Ubuntu.

sudo bash  
#enter pw  
apt-cache search ruby  
#should come up with something similar to ruby-1.8.2 or something of  
that nature  
apt-get install ruby-1.8.2  
#this will install it. For any gems in the future simply type:  
gem install

I apologize i also forgot to include that you need to run this before  
gem install.

apt-cache search rubygems # some rubygem installation will be listed  
apt-et install rubygems-version
