postgres on a FreeBSD 4.5 box

I've installed postgres 7.1.3 on a FreeBSD 4.5 box using the ports
system, I just can't seem to get it working.

su-2.05a# /usr/local/etc/rc.d/010.pgsql.sh status
pg_ctl: postmaster or postgres is not running
su-2.05a# /usr/local/etc/rc.d/010.pgsql.sh start
pg_ctl: postmaster does not start


(It takes a few seconds for the "postmaster does not start" to be
printed to the terminal, in the
mean-time I try to start psql at the prompt in someother terminal and
get the following:
[ken@localdev ken]$ psql
psql: connectDBStart() -- connect() failed: Connection refused
        Is the postmaster running locally
        and accepting connections on Unix socket '/tmp/.s.PGSQL.5432'?
[ken@localdev ken]$ ls -l /tmp/.s.PGSQL.5432*
srwxrwxrwx  1 postgres  wheel   0 Oct 30 15:48 /tmp/.s.PGSQL.5432
-rw-------  1 postgres  wheel  28 Oct 30 15:48 /tmp/.s.PGSQL.5432.lock
[ken@localdev ken]$ uname -a
FreeBSD localdev.stockbyte.com 4.5-RELEASE FreeBSD 4.5-RELEASE #0: Mon
Jan 28 14:31:56 GMT 2002
murray@builder.freebsdmall.com:/usr/src/sys/compile/GENERIC  i386

What do I need to do to get this working?
