This directory (and version of CentOS) is deprecated. For normal users,
you should use /6/ and not /6.2/ in your path. Please see this FAQ
concerning the CentOS release scheme:
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.
