PHP Fatal error

I'm getting the following errors:

PHP Fatal error: require_once() [<a href='function.require'>function.require</a>]: Failed opening required 'Zend/Validate/Abstract.php' (include_path='.:/usr/lib64/php:/usr/lib/php') in /updates/concrete5.4.2.2/concrete/libraries/3rdparty/Zend/Validate/GreaterThan.php on line 25

Also getting a warning:
PHP Warning: require_once(Zend/Validate/Abstract.php) [<a href='function.require-once'>function.require-once</a>]: failed to open stream: No such file or directory in /updates/concrete5.4.2.2/concrete/libraries/3rdparty/Zend/Validate/GreaterThan.php on line 25

These are not affecting my site as far as I know but wondering if I can get rid of them since at least some of these seem to be prevalent on all my C5 sites.
