Andy Jaworski already replied that rgdal Windows binaries are available 
from CRAN mirrors, thanks to Uwe Ligges.

For Mac OSX, please consult the detailed instructions on:

http://www.r-project.org/Rgeo -> Maps (in the left navigation bar).

Hint: see the configure.args= argument of install.packages() and use 
--with-gdal-config= to get the address right.

No Mac OSX binaries will be provided from CRAN, there are simply too many 
Mac OSX varieties out there to be sure that the installed external 
software harmonises with the rgdal binary build. However, one way of 
getting there is referenced in Rgeo, using William Kyngesburye's 
frameworks (rgdal binaries are provided in harmony with PROJ.4 and GDAL).

By the way:

RSiteSearch("rgdal macosx")

first hit takes you to a recent reply on this topic on the R-sig-geo list.
