error to install SAP BO 4.1 SP1 in Linux 6.7 (Santiago)

Hi,

I am trying to install SAP Business Objects 4.1 SP1 in Linux Red Hat 6.7 (Santiago), but when I run the installer, I have the next error:

Check Prerequisites

Summary of any missing critical or optional prerequisites.

Failed: Operating system patch level (Critical)

          Information: Missing patch: libXext-devel-1.1-3.el6.i686

Missing patch: libXext-devel-1.1-3.el6.x86_64

Has anyone had the same problem?, What I can do to correct it?

Regards.
