You need a file called PACKAGES in the same directory as the packages, which contains the package information; for example http://www.cran.mirrors.pair.com/bin/windows/contrib/1.9/PACKAGES I imagine the CRAN maintainers have scripts to produce this from the package files, but I'm not sure where they are. To refer to a local version of this file, use the syntax you had, e.g. CRAN.packages(contriburl="file:c:/temp") will look for c:/temp/PACKAGES and display the information in it. If you don't want to maintain this file, then you can construct the information in it using the "available=" argument to the package functions.
