[R-sig-Geo] spgrass6 build error on Mac OS X

[Thomas.Adams at noaa.gov]

List,

I am attempting to build spgrass6 on MacOS X 10.5.1 (Leopard) on a 2.33. GHz Intel Core Duo MacBook Pro. Using the Mac OS X Cocoa GUI, I am trying to install spgrass6 from source. I have gdal installed fine; when I run gdal-config at a term window prompt, I get:

Macintosh-2:bin teaiii$ gdal-config
Usage: gdal-config [OPTIONS]
Options:
	[--prefix[=DIR]]
	[--libs]
	[--dep-libs]
	[--cflags]
	[--version]
	[--ogr-enabled]
	[--formats]

I have "Install dependencies" checked, so rgdal is downloaded and attempts to build first. (No MacOS X binaries are available). So, I get:
