I do not think Oracle MessageQ 5.0 is supported/certified on RedHat Linux 6.x .
The latest rolling patch for OMQ 5.0 is RP053 but your patch, RP041, is the latest one available for the Linux platform.
If you wish OMQ 5.0 RP053 to be made available for RedHat Linux 5.x you will need to open a service request with support to have that rolling patch created.
Tuxedo 12 will include a "Tuxedo MessageQ" capability and may be something you want to investigate. GA for Tuxedo 12 is this summer.
Are there plans to continue support for MessageQ on the newer releases of Red Hat Linux?
Are there plans to certify on RHEL 6.x?
...or is this the end of the line and the go forward solution will be "Tuxedo 12 - MessageQ"?
