Server installation problem using freebsd ports

Hi,

This might be a very small problem but I am stuck. When I try to
install postgresql server 8.3.3 on freebsd using ports, I am getting -
  "postgresql-server-8.3.3 cannot install: unknown PostgreSQL version:
83"
I was able to install client. This has something to do with pgsql_ver.
What's wrong here?

Thanks
