Problems at the last step of installation

[neko940709]

Hi,
I have got some problems at the last step of installing the PG-STROM.
The whole installation process was consulted the steps in this website: https://wiki.postgresql.org/wiki/PGStrom#Sizing_Guideline , and I have done the installation of CUDA 8.0,PostgreSQL 9.5 and PG-STROM. Moreover, I modified the postgresql.conf already. But when I started the pgsql,the LOG message only shows like this:

-bash-4.2$ pg_ctl start -D /usr/local/pgsql/data/
server starting
-bash-4.2$ LOG: database system was shut down at 2016-12-11 14:16:39 CST
LOG: MultiXact member wraparound protections are now enabled
LOG: database system is ready to accept connections
LOG: autovacuum launcher started

The postgresql.conf likes this:

# - Kernel Resource Usage -

#max_files_per_process = 1000           # min 25
                                        # (change requires restart)
#shared_preload_libraries = '/usr/local/pgsql/lib/pg_strom'             # (change requires restart)

I also tried the '$libdir/pg_strom' ,but neither of them worked.
I'm so confused about it. Did I miss something?
Thanks for your reply.
