Hello

I already used rgdal successfully on Mac and on Linux/Ubuntu...

Now I try to make it work on Windows 7 (64 bit).

I have installed GDAL 1.9.1 on my system, but when I do : library(rgdal), I
get this:

/Geospatial Data Abstraction Library extensions to R successfully loaded
Loaded GDAL runtime: GDAL 1.9.0, released 2011/12/29
Path to GDAL shared files: C:/Program Files/R/R-2.15.0/library/rgdal/gdal
Loaded PROJ.4 runtime: Rel. 4.7.1, 23 September 2009, [PJ_VERSION: 470]
Path to PROJ.4 shared files: C:/Program Files/R/R-2.15.0/library/rgdal/proj/

I know that for Mac and Linux, rgdal uses the drivers of the gdal-version
installed on the system...

On Windows it seems to be different, I already change my GDAL_DATA and
GDAL_DATA variables, it didn't helped...

What I need arer the Postgisraster and the PostgreSQL driver...

Anybody has an idea how I could change this?

Thanks a lot
