I’m trying to install Capistrano. When I run gem install Capistrano  
–include-dependencies, I get the following error:

ERROR: While executing gem … (Zlib::BufError)  
buffer error

Anyone got any ideas what’s causing this and how I can fix it? I’d  
really like to use Capistrano to deploy my rails app, but I need to  
install it first…

Thanks,  
Myron

Actually, I did some more google searching and found the solution at:

Basically, I just had to update my RubyGems using gem update --system.
