Answer 1

Ruby can't find any root certificates to trust.

Take a look at this blog post for a solution: "Ruby 1.9 and the SSL error".

The solution is to install the curl-ca-bundle port which contains the same root certificates used by Firefox:

sudo port install curl-ca-bundle

and tell your https object to use it:

https.ca_file = '/opt/local/share/curl/curl-ca-bundle.crt'

Note that if you want your code to run on Ubuntu, you need to set the ca_path attribute instead, with the default certificates location /etc/ssl/certs.
