R help - Dec 2007 - options("defaultPackages") was not found [C1]

hello, i'm having a problem creating a custom package.
i've found other posts on the web that describe a similar problem but i
haven't found any solution.  please advise.

the error in the build process is
checking DESCRIPTION meta-information ... ERROR
During startup - Warning messages:
' in: library(package, lib.loc = lib.loc, character.only = TRUE, logical
TRUE,
 in options("defaultPackages") was not found



my r source (in the file dlog.r)

dlog <- function(X,h=1) {
list(res=(as.matrix(diff(log(X),lag = h, differences = 1))), res2=h)
}

1.  in RGui
source("C:\\shaun\\projects\\rpackagecreation\\dlog.r")

then

package.skeleton(name="DLOGPackage", list=ls(), .GlobalEnv,
"C:\\shaun\\projects\\rpackagecreation", TRUE)

2.  in the R install\bin directory i ran
rcmd build --force --binary --no-vignettes --docs=none
c:/shaun/projects/rpackagecreation/DLOGPackage

and i get the following message

* checking for file
'c:/shaun/projects/rpackagecreation/DLOGPackage/DESCRIPTION' ... OK
* preparing 'c:/shaun/projects/rpackagecreation/DLOGPackage':
* checking DESCRIPTION meta-information ... ERROR
During startup - Warning messages:
