rgdal loading problem...

R-sig-geo'ers:

I'm trying to get the Eclipse plugin for R ("Stat-et") working, but I've
run into a curious problem with rgdal I was hoping to get some help with.
 When loading rgdal from within the remote connection in Eclipse, I get
this error:

require("rgdal")

Loading required package: rgdal
Error in dyn.load(file, DLLpath = DLLpath, ...) :
  unable to load shared object
'/usr/apps/oa/lib64/R/library/rgdal/libs/rgdal.so':
  libgdal.so.1: cannot open shared object file: No such file or directory

Other packages work fine via the remote "load", e.g.:

require("raster")

Loading required package: raster
raster version 1.9-64 (16-January-2012)


Curiously, when launch of R via the command line (connecting to the same
server as above via SSH) I get the normal, no-problem load:

require("rgdal")

Loading required package: rgdal
Loading required package: sp
Geospatial Data Abstraction Library extensions to R successfully loaded
Loaded GDAL runtime: GDAL 1.9.0, released 2011/12/29
Path to GDAL shared files: /usr/apps/oa/share/gdal
Loaded PROJ.4 runtime: Rel. 4.7.1, 23 September 2009, [PJ_VERSION: 470]
Path to PROJ.4 shared files: (autodetected)

I suspect something is going on with the environment variables between the
Stat-ET launching of R, and the command-line launching.  A Sys.getenv()
reveals that the environment variables are different, but I'm unclear which
variable(s?) I should be looking for to fix this problem (or perhaps it is
another issue altogether).  Thoughts?  Cheers!
