The Laravel docs mention adding guzzlehttp/guzzle ~4.0 to composer.json for use with Mandrill’s API.
At the time of writing GuzzleHTTP 5.2 was current. Unclear why 5.2 is not suitable, but it gave the SSL Error 60 locally.
[code]
"require": {
"laravel/framework": "4.2.*",
"guzzlehttp/guzzle": "~4.0"
}[/code]
Seemed to fix it on Windows 8. PHP 5.6
