* If node will run postgresql, you'll need to do the trick: add postgresql server as a package first, then build databases/py-psycopg2 from ports with python 2.7:
```shell
root@noc:~ # pkg install -y postgresql95-server
root@noc:~ # sysrc postgresql_enable="YES"
root@noc:~ # cd /usr/ports/databases/py-psycopg2
root@noc:~ # sed -i.bak 's/^\(USES.*python\)/\1:2.7/' Makefile
