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.
COMMAND PROMPT: export SSL_CERT_DIR=/etc/ssl/certs
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"
