Description of problem:
There has been a problem with apr when the EAP team is testing with mod_cluster.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
Here's the description from the JIRA:

With this httpd and this mod_cluster dist, having the undermentioned config:

<IfModule manager_module>
  Listen [2620:52:0:105f::ffff:c]:8888
  NameVirtualHost [2620:52:0:105f::ffff:c]:8888
  <VirtualHost [2620:52:0:105f::ffff:c]:8888>
   ServerName vmg35
   ServerAlias *.vmg35
   <Directory />
     Order deny,allow
     Deny from all
     Allow from all     
   AdvertiseGroup [ff01::1]:6666

   <Location /mcm>
       SetHandler mod_cluster-manager
       Order deny,allow
       Deny from all
       Allow from all


I am getting the following:

[notice] Apache/2.2.17 (Unix) DAV/2 mod_cluster/1.2.1.Final configured -- resuming normal operations
[error] (22)Invalid argument: mod_advertise: ma_group_join apr_mcast_hops failed
[error] (22)Invalid argument: mod_advertise: multicast join failed for ff01::1:6666.

The Mod_cluster manager console shows loaded mod_cluster:

[hudson@vmg35 httpd]$ telnet 2620:52:0:105f::ffff:c 8888

Additional info:
The issue has been reported for RHEL 6 in https://bugzilla.redhat.com/show_bug.cgi?id=824515
We'll need the same fix for apr in base REHL 5.

The complete patch that will be used for RHEL 6 is http://svn.apache.org/viewvc?view=revision&revision=1309394.

Removed rhel-5.8.z flag as RHEL-5.8 is EOL.
