Twilio app; twilio-ruby (3.4.2), SSL error - ruby

Question

I have followed the sample code on the Twilio github page and it doesn't work. In my Rails console, it looks like this:
irb(main):039:0> require 'twilio-ruby'
=> nil
irb(main):040:0* account_sid='xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx'
=> "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"
irb(main):041:0> auth_token='yyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyy'
=> "yyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyy"
irb(main):042:0> client=Twilio::REST::Client.new account_sid, auth_token
=> <Twilio::REST::Client #account_sid=AC1322312300a752f6e84a8254535ecce5>
irb(main):043:0> client.account.sms.messages.create :from=>'16135551234', :to=>'16135551212', :body=>"Ada is fat"

What else do I need to do to get twilio-ruby to successfully send a text message? I have used these numbers and credentials for incoming calls, so they are good.
** EDIT Dec 24, 2011 ***
Instead of running this code on my PC, I deployed it to heroku.com. Then I had no SSL errors and I was able to place outgoing calls. I'm very puzzled.

Answer 1

This shouldn't be a problem in twilio-ruby versions starting with 3.5.0. It "just works" out of the box now.
With twilio-ruby versions before 3.5.0 there wasn't an SSL CA cert bundle packaged with the gem. So the only way to "fix" this was to either point your client at a cert bundle at initialization time:
client = Twilio::REST::Client.new sid, token, :ssl_ca_file => '/path/to/file'
or to disable SSL verification altogether (not recommended in production):
client = Twilio::REST::Client.new sid, token, :ssl_verify_peer => false

Answer 2

You may be missing root certificate files. This typically shouldn't be necessary but you can try disabling certificate verification by adding these lines before making the call:
require 'open-uri'
require 'openssl'
OpenSSL::SSL::VERIFY_PEER = OpenSSL::SSL::VERIFY_NONE
