file format error with R and GRASS61

I am trying to figure out an GDAL error message about grass file not  
being a supported format. The message is:

 > gmeta6 <- gmeta6()
 > fname <- paste(gmeta6$GISDBASE, gmeta6$LOCATION_NAME,
+ "PERMANENT", "cellhd", "soils.ph",
+ sep="/")
 > soilsph_GDAL <- read.GDAL(fname)
Error in .local(.Object, ...) :
         GDAL Error 4: `~/grassdata/spearfish60/PERMANENT/cellhd/ 
soils.ph' not recognised as a supported file format.
If r.out.gdal works for you on that file, then we have a problem. However, 
I think that your GRASS GDAL plugin is not present, so GDAL doesn't know 
how to read GRASS rasters natively. What does
getGDALDriverNames()
say within R after loading the rgdal package, or equivalently

$ gdalinfo --formats

from the shell prompt? If you see "GRASS" there, we have a problem, if 
not, please make sure the GDAL GRASS plugin is installed and working (one 
does this *after* installing GRASS.

This is on grass61 and R 2.2.1 using the spearfish60 location

Thanks in advance for any ideas
