Macports installs its packages in folders that are not standard and  
then R packages don't find them (at least that's my understanding of  
the reason Macports causes troubles with R packages.) You are asked  
not to use it for packages that R will be linking to. So maybe that  
error will be a boon rather than a bane. Doing a search on: [ macports  
Urbanek]  in the archive of r-sig-mac should provide further details.  
This really should have been posted there.

GDAL is an external package. http://trac.osgeo.org/gdal/wiki/DownloadingGdalBinaries

rgdal is the R interface package that you would use to get GDAL  
functionality.
