Libcap error on Linux Centos 6.3 server

Trying to install Adobe Flash media Server on my Linux Centos 6.3 server and am getting the error :

ERROR : A required package, libcap, was not found on your Linux X86_64 Redhat.

Please install required package and run Adobe Flash Media Server installer again

Then put in the "yum -y install libcap"

and it said :

Package libcap-2.16-5.5.e16.x86_64 already installed and latest version.

Is this actually the latest version of libcap?

what do i have to do to get this working?

Thank you!
