Tim,

One way of handling this might be - if you will only use rgdal from 
"within" GRASS, is to run the install from the rgdal source package in 
that environment. Alternatively, use gdal-config within GRASS to find the 
the GDAL libs (--libs) and headers (--cflags) strings to pass to the 
configure arguments in install.packages() in R outside GRASS. Here rgdal 
will fail after installation if the GDAL shared objects are not on the 
PATH R can see.

Hope this helps,

Roger
