PostgreSQL 9.1 SPI

[Puneet Kishor]

I was hoping to try out the SPI extension with Postgres 9.1, which, per the documentation at http://www.postgresql.org/docs/9.1/static/contrib-spi.html is supposed to live under <path>/to/contrib. But, in my /opt/local/share/postgresql91/contrib I don't have spi. Should I be able to get this via macports, or do I just download Pg sourcecode and look within that?
