Install/build for Talpa fails on RHEL 7.5

Question

Basic server information: 
 This is a RHEL 7.5 server 
 # gcc --version gcc (GCC) 4.8.5 20150623 (Red Hat 4.8.5-28) Copyright (C) 2015 Free Software Foundation, Inc. This is free software; see the source for copying conditions. There is NO warranty; not even for MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. # uname -r 3.10.0-862.3.2.el7.x86_64 
 There are no custom builds, all standard software on this host. GCC and the kernel-devel packages were installed directly from the RHEL repo. The initial install failed to install the Talpa stuff, so I tried to manually build it with the 'talpa_select select' command. This is what I am seeing in the logs, and I am at a loss:

Talpa 1.23.6 doesn't support RHEL 7.5, since Redhat changed the kernel in a way it doesn't support. 
 
 If you configure updating, Talpa will be upgraded to 1.23.8 which does support RHEL 7.5 (hence why the online list of TBPs includes that kernel). 
 
 In general you need to have updating working to get recent kernel support, sometimes including using git to get even more up to date Talpa source, although that isn't required in this case.
