Title: Curl requirement for Guzzle\Http composer

I get an error while using the Guzzle\Http component because my php was missing curl, and i think it would be great if i get warned in the installation process.

Detail:
PHP Fatal error: Call to undefined function Guzzle\Http\Curl\curl_version() in /path/to/project/vendor/guzzle/http/Guzzle/Http/Curl/CurlVersion.php on line 47
