Hi Leonardo,
One step resolution can be found on 1997565 - Error: "Failed: Operating system patch level (Critical)" while installing SAP BusinessObjects Business Intelligence 4.1 on Red Hat Enterprise Linux 6.4
Note : above KBA can be used for your operating system as it is minor upgraded version.
If you are unsure of installing it ask your Linux admin to install 2 libraries :
- libXext-devel-1.1-3.el6.i686
- libXext-devel-1.1-3.el6.x86_64
After that you as a perk you can use this link to install the product step by step with screenshots : http://scn.sap.com/community/bi-platform/blog/2013/11/06/installing-sap-bi-41-sp01-on-red-hat-enterprise-linux-6x-step-by-step
Hope this will help you to resolve the issue and to install it too.
Regards,
Mahak
