[R-sig-Geo] libproj errors

Friends,

    I recently became a GRASS convert. I have been an R user for a long 
time, so naturally I have tried spgrass6.  Unfortunately I have yet to 
get it to work.  The beginning goes well

 > library(spgrass6)
Loading required package: sp
Loading required package: rgdal
Geospatial Data Abstraction Library extensions to R successfully loaded
Loaded GDAL runtime: GDAL 1.5.3, released 2008/09/09
Path to GDAL shared files: /usr/share/gdal
Loaded PROJ.4 runtime: Rel. 4.6.1, 21 August 2008
Path to PROJ.4 shared files: (autodetected)
Loading required package: XML
GRASS GIS interface loaded with GRASS version: 6.3.0
and location: grte

but then (despite the reference to PROJ.4 above) when I try and get a 
raster into R I get an error

 > test <- readRAST6('elev_30')
Error in .local(.Object, ...) :

	GDAL Error 1: libproj.so: cannot open shared object file: No such file 
or directory

but it appears to be there (twice actually)

 > system('find /usr -name libproj.so')
/usr/local/lib/libproj.so
/usr/lib/libproj.so

I copied it from usr/local/lib to usr/lib thinking maybe it wasn't 
looking at the right path, but it doesn't seem to find it in either 
location.  This appears to be a GDAL error, rather than an R or spgrass6 
error, but GRASS runs fine.

FWIW I'm running Fedora 10 x86_64, GRASS 6.3, GDAL 1.5.3, PROJ.4 4.6.1

Thanks in advance for any help, Dave
