Postges 11 Proj Dep Error CentOS 7

Using repo on CentOS 7, along with epel7, PostGIS 2.5 installs without error, but adding extension throws error below.
'/usr/pgsql-11/lib/postgis-2.5.so: undefined symbol: geod_polygon_init'

This seems to be the result of the pg repo using proj from epel (which is version 4.8) to meet dep, while the pg repo version is the required 4.9

> Installed Packages
proj.x86_64                               4.8.0-4.el7                    @epel
proj49.x86_64                             4.9.3-3.rhel7.1                @pgdg11

Have tried remove/install but pg repo just pulls in proj from epel again.

Thanks,

Scott
