Installing module for 9.6, not 9.2, on Centos?

Hi. I recently installed 9.6 on my Centos 6.9 server, alongside a
still-running 9.2.

I need to install a module for 9.6 (table_log) that is installed on 9.2.
I took the table_log Makefile and changed it to point to
/usr/pgsql-9.6/bin/pg_config
instead of 9.2. It is still installing into the 9.2 directory though.

What's the cleanest or most proper way to target 9.6 in this situation?
Transcript below, and TIA.
