Use postgresql91 by default in py26-mapnik port

[shirshegsm@…]

Makes sense as 9.1 is default in most other places as far as I've checked.

Please attach a unified diff of the port file so we can easily see the changes you made.

Portfile patch

[larryv (Lawrence Velázquez)]

Is Mapnik directly dependent on PostgreSQL? Since PostGIS already requires an appropriate version of PostgreSQL depending on its variant, does this port have to have a dependency on it also?

What if postgis +postgresql90 is installed? py26-mapnik is going to force installation of postgresql91 anyway.

[dbsgeo@…]

Mapnik does not depend on postgres. Mapnik uses a plugin architecture for datasources, so if postgres is available the "postgis.input" dynamic library is built so Mapnik will have postgres read support. Mapnik 2.0 (the latest release) supports all modern versions of postgres and postgis.

[larryv (Lawrence Velázquez)]

Right, so all it needs for PostGIS support is the postgis port. But the current portfile and the patch attached here currently declare a direct dependency on PostgreSQL:

variant postgis description {Builds port with PostGIS plugin} {
    depends_lib-append      port:postgresql84
    depends_lib-append      port:postgresql84-server
    depends_lib-append      port:postgis
    configure.args-append   PG_CONFIG=${prefix}/lib/postgresql84/bin/pg_config
}

Should those be removed then?
