Mac postgres/postgis driver for rgdal

I'm trying to get rgdal to read polygon data directly from a postgis-enabled database, but things aren't working too smoothly. I'm using OSX 10.9.2 with R 3.0.2 and I have the complete GDAL 1.10.1 framework installed from Kyngchaos. Specificlly this: http://www.gdal.org/ogr/drv_pg.html is the driver I want. I've confirmed that /Library/Frameworks/GDAL.framework/Versions/Current/Libraries/libpq.dylib exists - as I currently understand it this is the driver I need.

The rgdal package is compiled from source against the installed gdal framework using:

sudo R CMD install rgdal_0.8-16.tar.gz --configure-args='--with-gdal-config=/Library/Frameworks/GDAL.framework/unix/bin/gdal-config --with-proj-include=/Library/Frameworks/PROJ.framework/unix/include --with-proj-lib=/Library/Frameworks/PROJ.framework/unix/lib'

which completes successfully. There's no issue loading rgdal, but the postgres driver refuses to appear:

Am I missing something obvious?

(EDIT: Note that ogrinfo "PG:[conneciton string here]" works perfectly, so the driver is certainly working)

Solution

Sorry for the self answer, but I've solved it.

Forget the rgdal package you get from the CRAN repos, it includes its own basic gdal which doesn't have the necessary driver. I still don't understand why compiling from source didn't work, but regardless you can get a copy of rgdal which does work from:
