(The R-sig-geo mailing list may be a more appropriate place to look for an
Unfortunately, I as maintainer of the package have no access to OSX. I do
know that OSX users have installed rgdal successfully, and installation
instructions are on the Rgeo website:
"OSX: The rgdal source package from CRAN can be installed on OSX by first
installing PROJ.4 and GDAL, then installing sp, and finally download the
source package tarball to a suitable temporary location, and install with
R CMD INSTALL ... your options ... rgdal*.tar.gz. Your options give the
locations, if required, of --with-gdal-config=, --with-proj-include=,
and/or --with-proj-lib=, all within --configure-args='' as described in
section 1.2.2 of the ''Writing R extensions'' manual."
But this presupposes that you can find the installed software on your
system yourself, something that is difficult to do at a distance. If OSX
has the locate utility, you could run it in a terminal, or search for the
files needed (in Finder??), but an OSX user would know the correct way
forward. I expect that you have installed PROJ.4 too - do either of
proj -lp or gdalinfo --formats or ogrinfo --formats at a terminal prompt
say anything useful to indicate that the applications using the libraries
are available and working?
