libxml2.so.2 Cron Error

Hi, a cron job I've had set up for over a year now has been running fine but today I've been receiving the error to my email from Cron Daemon:
php: /opt/xml2/lib/libxml2.so.2: no version information available (required by php)

Is this something I need to update on my end via my WHM?

Thanks!,
Wesley
