This directory (and version of CentOS) is depreciated. For normal users, you should use /6/ and not /6.2/ in your path. Please see this FAQ concerning the CentOS release scheme: http://www.centos.org/modules/smartfaq/faq.php?faqid=34 If you know what you are doing, and absolutely want to remain at the 6.2 level, go to http://vault.centos.org/ for packages. Please keep in mind that 6.0, 6.1 and 6.2 no longer gets any updates, nor any security fix's.
