R devel - Jul 2010 - R CMD check - "there is no package called"

I'm trying to update my "perturb" package to get rid of some small
warning
messages. The examples in "perturb" use the "Duncan" dataset
from the "car"
package and I have "car" installed in R. But when I run "R CMD
check", I get an
error message 

> require("car")
Loading required package: car
Warning in library(package, lib.loc = lib.loc, character.only = TRUE, 
logical.return = TRUE,  :
  there is no package called 'car'
> data(Duncan)
Warning in data(Duncan) : data set 'Duncan' not found

This is very strange, the example works fine if I just run it in R. This is the 
example from the perturb.rd file:

  \examples{
require("car")
data(Duncan)
attach(Duncan)
m1<-lm(prestige~income+education)
...

I'm using R 2.11.1 under Ubuntu 10.04. Perhaps the problem is related to the
packages being installed in my home directory. I've create an ~/.Renviron
file
with 

R_LIBS_USER="/home/john/lib/R/library"

I've also tried creating an environment variable "export 
R_LIBRARY_DIR=/home/john/lib/R/library/" before running R CMD check. That
made
no difference. Can anyone point me in the right direction? Do I have to install 
packages in R_HOME?

The correct name is R_LIBS
