Class 'Symfony\Component\Yaml\Yaml' not found

Hi Guys,


I'm attempting to install the lastest version supplied on GitHub (PHP-SDK) and after getting composer installed and running the config both provided in the files I downloaded and other configurations people have posted, I cannot get past this error.  Doing a search I'm not the only one with this issue but I cannot find any resolution for it. It would be nice if I could get a link to the files I should be downloading and putting on my server (since its not on the site, they only link to sample codes), a document that tells me the hierarchy the system expects its files to be in when uploaded and a correct / updated composer.json file that we're actually supposed to use (the readme file is different than the included file...).


PHP Fatal error:  Class 'Symfony\Component\Yaml\Yaml' not found in ...jms/serializer/src/JMS/Serializer/Metadata/Driver/YamlDriver.php on line 35


Does anyone have directions on fixing this problem?
