I was trying to deploy an older Rails 2.2.2 app to a new server and when I started up the application, I ran into the following error:

in `require_frameworks': no such file to load -- openssl (RuntimeError)

Hmm…my app doesn’t even use SSL. Whatever…(think this is because capistrano is involved?)

To fix this, I installed openssl by running

sudo apt-get install libopenssl-ruby1.8

Success!
