I hope you find this, it will save you hours of googling.
Are you getting a certificate verify failed error in Ruby 1.9? I had this problem while trying to use Amazon's MTurk / Mechanical Turk api for AWS. It could honestly be ANYTHING that tries to connect to another website that might have this error come up. Have you found a billion websites that suggest doing something like turning off SSL verification. Well, that would work. Or you could fix this damn problem.
If this helped you at all, you owe me a link back to my blog. Wasted a ton of time finding this. XD

Things not to waste time with (that might work):
- OpenSSL::SSL::VERIFY_PEER = OpenSSL::SSL::VERIFY_NONE
- http.ca_file = "/etc/ssl/certs/ca-certificate.crt"
