I had an awful time today trying to install the HighLine gem on my  
machine at home. After several attempts, I tried disabling my firewall  
on a whim, and presto, the gem installed successfully. I don’t recall  
having this problem with other gems in the past, so I am wondering if  
my trouble had to do with where the HighLine gem resides? Is there a  
specific port that gem installs communicate on? How should I setup my  
firewall to allow gem installs?

Thanks  
Jay

RubyGems uses port 80.
