Initalizing PostgreSQL Database

I'm getting the following error message when I try to create a user or database
on postgresql 7.2.2 on Freebsd 4.7, I installed it from the ports directory but
I'm stumped when I got the following error message. When I do a
/usr/local/etc/rc.d/010.pgsql.sh start all I get is this:

freebsd# sh 010.pgsql.sh start
 pgsqlfreebsd#



$ createdb test1
psql: could not connect to server: No such file or directory
        Is the server running locally and accepting
        connections on Unix domain socket "/tmp/.s.PGSQL.5432"?
createdb: database creation failed
