GRASS needs to be compiled with Postgres support to be able to store attribute data in Postgres.  Last I checked it doesn't handle Postgis directly, it's an import and uses GDAL, so it doesn't need Postgres support for that.

Bad form really, because you can't expect modules to work between different builds of python, even if they're the same version.  Maybe there is some option in Macports python to exclude the system site-packages.
