[R] Problems with loading arm

Hello,

I recently updated to R 2.10 on my 64 bit Dell Precision T7400 running
Enterprise Linux and now I can't get the arm library to load when I run
R using Wine.  Prior to the update I was able to use arm without any
trouble.  My main goal is to use arm with WinBUGS on this machine,
calling it from R for Windows, which is executed with wine.  After the
update, when I try to load the arm library, I get the following:

> library(arm)
Loading required package: MASS
Loading required package: Matrix
Loading required package: lattice
Loading required package: lme4
Loading required package: R2WinBUGS
Loading required package: coda

Attaching package: 'coda'


         The following object(s) are masked from package:lme4 :

          HPDinterval

Loading required package: abind
Loading required package: car
Error in packageDescription("arm", lib = mylib)$Version :
   $ operator is invalid for atomic vectors
In addition: Warning message:
In packageDescription("arm", lib = mylib) : no package 'arm'
was found
Error : .onAttach failed in 'attachNamespace'
Error: package/namespace load failed for 'arm'

I tried reinstalling arm (and updating all packages), but I still get
the same error.

I've tried loading arm in R running under linux pointing to the library
location that R for Windows is reading from and it loads fine.  I've tried
loading arm in R for Windows referencing the library location where I've
installed arm for R for linux, and get the following:

> library(arm)
Loading required package: MASS
Loading required package: Matrix
Loading required package: lattice
Loading required package: lme4
Error in library.dynam(lib, package, package.lib) :
   shared library 'lme4' not found
Error: package 'lme4' could not be loaded

I installed lme4 in the same directory as arm (i.e., myrlibrary/), but R
claims it can't find it, even though it shows up in the window when I
click on "Load Packages...".  I'm assuming this has something to
do with
a shared library problem.

I've spent the past two days googling, reading manuals and standard
references, and I'm stumped.  Does anyone have any suggestions about how
I might fix this problem.

Best,
Greg
