None of that refers to anything that is part of RT. That's a version 
number for the *OBSOLETE* Perl module IO::Socket::INET6.

Nothing should be using IO::Socket::INET6. It is abandoned (note 
https://bitbucket.org/shlomif/perl-io-socket-inet6/overview) and has 
been superseded by IO::Socket::IP. If you can't convert whatever is 
using it to use IO::Socket::IP, I guess you could upgrade to to the last 
version but it would be a bit like running Windows ME: no one else uses 
it *BECAUSE IT'S SHODDY*, no one cares about any bugs you might run 
into, and nothing else you want to run will accommodate the quirky 
exercise in inscrutable nostalgia.
