The CURL_SSLVERSION_TLSv1 constant was only added in PHP 5.5 and will cause issues for prior versions. I suggest you change it to the numeric value 1 unless we are changing the min PHP version for LTS.

While PHP 5.4 and 5.5 are officially EOL, I think that since some popular Linux distros are still supporting PHP 5.4 (Debian Jessie, CentOS 7, Ubuntu 12.04 LTS) that 5.4 should probably remain supported for now. Should be easy to add fix: defined('CURL_SSLVERSION_TLSv1') ? CURL_SSLVERSION_TLSv1 : 'TLSv1'

actually CURL_SSLVERSION_TLSv1 resolves to just 1, which is now used by magento in the newest version.
