Problem with Libevent updating from CentOS 6.7 to 6.8, PostgreSQL 9.3

I'm seeing what I believe to be a similar problem to:
https://www.postgresql.org/message-id/1403098731.14178.6.camel%40asus-laptop-03.gunduz.org

My system:

# uname -a
Linux cs.drew.edu 2.6.32-573.18.1.el6.x86_64 #1 SMP Tue Feb 9 22:46:17 UTC

Distributor ID: CentOS
Description: CentOS release 6.7 (Final)
Release: 6.7
Codename: Final

It's happening on a few systems with CentOS 6.7 and pgsql 9.3 installed
from the 9.3 repo. We've got a couple of packages that only support 9.3.

In my case, yum is failing with:

Transaction Check Error:

I'm wondering if the compat-libevent14 problem that apparently existed in
the 9.4 and 9.5 repo is also present in 9.3? If so, is it possible to get
that fixed? Otherwise, any reasonable, low-risk workarounds?
